The product of the sum and difference of two terms can be found using the distributive property and the FOIL (First, Outer, Inner, Last) method.If you have two terms, A and B, the sum and the difference of these terms can be represented as:

Sum: A + B Difference: A - B

To find the product of the sum and difference, you can multiply the sum and the difference together:

(A + B)(A - B)

Using the distributive property, we can expand the product:

AA - AB + AB - BB

Which is equal to:

A^2 - B^2

This is the difference of squares of the terms.

It's worth noting that this is a very common pattern in algebra, and it's called the difference of squares. It is the product of the sum and difference of two terms. The distributive property and FOIL method can be used to expand the product of two binomials, but it's important to recognize patterns, like this one to solve the problem in a faster way.

45 is not a perfectly square, its square root is irrational. Because it cannot be written as the product of two integers of equal value, 45 is not a perfect square number.

Let's learn what the square root means before we get started. The mathematical concept of the square root is represented by the symbol. Any square root-related problem can be solved once you understand the fundamentals of the process. We will learn about the square root of 45 in this brief lesson. Methods like prime factorization and division will be used to accomplish this, as will the square root of 45.

45/square root: 45 x 6.708 is the square of 45: 452 = 2025

We are aware that the opposite of addition is subtraction, and the opposite of division is multiplication. Similar to squaring, finding the square root is the opposite of squaring. The number that is obtained when 45 is multiplied by itself is the square root of 45. Therefore, we must choose a number whose square is 45. As can be seen, there is no integer whose square is greater than 45. The number that is multiplied by itself to yield the original number is known as its square root.

The solution for the absolute function is h < 2.

The variable in the absolute value bars makes up an essential algebraic function known as the absolute value function. The most widely used version of the absolute value function is f(x) = |x|, where a = 1 and h = k = 0. The general form of this function is f(x) = a |x - h| + k.

When we extend the absolute value function f(x) = |x|, we can write it as x if x 0 and -x if x 0 since the range of this function, f(x) = |x|, is always non-negative.

The function will be solved as,

Transfer all terms to one side of the equation, usually the left, using addition or subtraction. Factorise the equation completely. Equate each factor equals zero, and then solve. Record each solution from Step 3 as a solution to the original equation.

For example, we have an equation x² + 2x = 8x – 8

Step 1. First, subtract 8x from each side.

x² + 2x – 8x = 8x – 8x – 8

x² – 6x = -8

Now, add 8 to each side.

x² – 6x + 8 = -8 + 8

x² – 6x + 8 = 0

Step 2. We identify the left as a trinomial and factor it accordingly:

(x – 2)(x – 4) = 0

Now the two factors are (x – 2) and (x – 4).

Step 3. Now we assigned each factor equal to zero.

(x – 2) = 0 and (x – 4) = 0

x = +2 and x = +4

Step 4. The last step is to join the two previously solved solutions, x = 2 and x = 4, into one solution for the original problem.

Step-by-step explanation:

We know

12 out of every 15 students owns a cell phone, so the ratio of student who owns cell phone is 12:3. For every 15 students, there are 12 own cellphones, and 3 do not.

To find there are 435 students surveyed, how many do not own a cell phone? We take

435 / 15 = 29

3 x 29 = 87 students

So, 87 students do not own a cellphone.

Using Algebraic expressions, the original length of the string was 72 feet.

When addition, subtraction, multiplication, division, and other mathematical operations are performed on variables and constants, the result is a mathematical statement known as an algebraic expression.

Let's say James and Natalie were playing with matchsticks when they had the idea to create number patterns with them. James made the number 4 with four matchsticks. In order to create a pattern with two 4s, Natalie added three extra matchsticks.

They understood that they could keep adding three matchsticks each round to make an additional "four" by doing so. They deduced from this that, generally speaking, in order to create a pattern with n number of 4s, you need 4+ 3(n-1) sticks. We refer to 4+ 3(n-1) as an algebraic expression in this case.

Let x be the length of the string,

when it is cut into 4 halves,

the length becomes x/4,

then it is again cut 1/3,

Now, it is given that 1/3 × x/4 = 6

⇒ x = 72

So, the original length of string was 72 feet.

If ∡DAB and ∡DCB are right angles and m∡ABD = 42°, then the measure of arc ACB is 264°.

What is an arc?

An "arc" in mathematics is a straight line that connects two endpoints. An arc is typically one of a circle's parts. In essence, it is a portion of a circle's circumference. A curve's arc is a component.

The angles ∡DAB and ∡DCB are right angles.

The measure of ∡ABD = 42°

It can be seen that ∠ABD is inscribed angle of arc AD, so the measure of arc AD is two times the measure of ∠ABD.

AD = 42° × 2 = 84°

It can also be seen that segment DB is diameter of given circle as inscribed angle of diameter is a right angle.

Since segment DB is diameter of given circle, so measure of arc DCB would be equal to half the measure of 360 degrees.

DAB = 360°/2

DAB = 180°

ACB = AD + DCB

ACB = 84° + 180°

ACB = 264°

Therefore, the measure of arc ACB is 264°.

The value of x from the triangle is x = 44°

A triangle is a plane figure or polygon with three sides and three angles.

A Triangle has three vertices and the sum of the interior angles add up to 180°

Let the Triangle be ΔABC , such that

∠A + ∠B + ∠C = 180°

The area of the triangle = ( 1/2 ) x Length x Base

For a right angle triangle

From the Pythagoras Theorem , The hypotenuse² = base² + height²

if a² + b² = c² , it is a right triangle

if a² + b² < c² , it is an obtuse triangle

if a² + b² > c² , it is an acute triangle

Given data ,

Let the triangle be represented as ΔABC

Now , the measure of side ∠A = 82°

The measure of side ∠B = 54°

The measure of side ∠C = x°

Now , for a triangle ,

∠A + ∠B + ∠C = 180°

Substituting the values in the equation , we get

82° + 54° + x° = 180°

On simplifying the equation , we get

136° + x° = 180°

Subtracting 136 on both sides of the equation , we get

x = 180° - 136°

x = 44°

Now , for a straight line , the angle in a straight line is 180°

So , x + y = 180°

Substituting the values in the equation , we get

44° + y = 180°

Subtracting 44° on both sides of the equation , we get

y = 136°

Now . the measure of z = measure of y ( alternate interior angles )

So , z = 136°

And , the measure of exterior angle of a triangle = sum of the opposite interior angle

Therefore , y = z = 136°

The dimensions of the scale drawing are 10cm x 16cm.

A scale drawing is a representation of an object or a space that is smaller or larger than the actual object or space. The scale of a drawing is represented as a ratio, such as 1:6, which means that every 1 unit on the drawing represents 6 units on the actual object or space.

In this case, we are given a rectangular flag that has dimensions of 60 cm by 96 cm, and a scale of 1:6. This means that for every 1 cm on the scale drawing, the actual flag is 6 cm. To find the dimensions of the scale drawing, we need to divide the dimensions of the actual flag by the scale.

To find the length of the scale drawing, we divide the length of the actual flag (60 cm) by the scale (6):

Length of scale drawing = 60 cm / 6 = 10 cm

To find the width of the scale drawing, we divide the width of the actual flag (96 cm) by the scale (6):

Width of scale drawing = 96 cm / 6 = 16 cm

So, the dimensions of the scale drawing are 10cm x 16cm.

The total price including tax, Fawaz has to pay is $36 round to the nearest cent.

To find the total price of the phone including tax, we need to add the tax amount to the price of the phone. The tax rate is 9%, which means that for every $1 of the price of the phone, $0.09 will be added as tax. To find the total price including tax, we can use the following formula:

Total price = Price of the phone + (Price of the phone x Tax rate)

Given the information in the problem, we know that:

Price of the phone = $33

Tax rate = 9% (expressed as a decimal)

Plugging these values into the formula, we get following equation:

Total price = $33 + ($33 x 0.09)

To solve for total price, we need to calculate ($33 x 0.09)

= $3

Total price = $33 + $3

Total price = $36

So the total price including tax, Fawaz has to pay is $36 round to the nearest cent.

In simple words, we have multiplied the price of the phone with the tax rate and then added the tax amount with the price of the phone to get the total price including tax.

Note: The tax rate is given as 9% which is equal to 0.09 in decimal form.

A point (x1, y1) is said to satisfy the inequality ax + by ≤ c if a(x1) + b(y1) ≤ c. The graph of a linear inequality is the set of all points in the plane which satisfy the inequality.

Now, the given equation is 2x + 3y ≥ 6

We can find multiple points (x, y) that satisfy the given inequality. For now, we can take the point (1,2).

To check if (1,2) satisfies the inequality, put x = 1, y = 2 in the inequality.

2 + 6 ≥ 6

8 ≥ 6, which is true.

This line cuts the plane in half. One half contains all points (x, y) with 2x + 3y > 6 and the other half contains all points with 2x + 3y < 6.

To find which half is which, we need only check one point on one side of the line. (if the line does not cut through (0, 0), we can check that point easily.) In this case we find that 2(0) + 3(0) < 6.

Therefore the solution to the inequality 2x + 3y ≥ 6 is the half plane not containing (0, 0) shaded below. We can also represent it with arrows as in the diagram on the right.

Since the region includes the points along the line 2x + 3y = 6, we draw a
