The solution to 3x + 2(4 + 6x) = 113 is x=7

3x + 2(4 + 6x) = 113

We will multiply the 2 with the brackets

3x+8+12x=13

adding the coefficients os x together

15x+8=113

adding -8 on both the sides

15x=105

dividing both the sides by 15

x=105/15

after division we get

x=7

To check our solution

we first put value of x in our original equation

3x7 + 2(4 + 6x7) = 113

we simplify the equation

21+2(4+42)=113

According to BODMAS we first solve the bracket

21+2(46)=113

now we solve the multiplication part

21+92=113

solving this

113=113

∴ LHS=RHS

Hence the solution is correct.

Therefore, the solution to 3x + 2(4 + 6x) = 113 is x=7

Answer:

sorry i don't know but you do it very good i promise

The numeric value of the function f(x) = 4x² + 2x + 2 at x = x + 2 is given as follows:

f(x + 2) = 4x² + 20x + 22.

To find the numeric value of a function or of an expression, we replace each instance of the variable in the function or in the expression by the value at which we want to find the numeric value.

The function for this problem is defined as follows:

f(x) = 4x² + 2x + 2

To obtain the numeric value at x = x + 2, we replace the two instances of x by x + 2, hence:

f(x + 2) = 4(x + 2)²  + 2(x + 2) + 2

f(x + 2) = 4(x² + 4x + 4) + 4x + 4 + 2

f(x + 2) = 4x² + 16x + 16 + 4x + 6

f(x + 2) = 4x² + 20x + 22.

The problem asks for the numeric value of the function f(x) = 4x² + 2x + 2 at x = x + 2.

The probability that both of them wear glasses is 35%.

The probability that both students wear glasses is equal to the product of the probability of the first and the second student wearing glasses

If 59% of all students on campus wear glasses, then the probability of a single student wearing glasses is 0.59.

The probability that both students wear glasses is:

0.59 * 0.59 = 0.3481

Approximate

0.59 * 0.59 = 0.35

A Boolean data type is a type of data that can have one of two possible values, either true or false.

Boolean values are used in logic and programming to make decisions and determine the flow of a program. In programming, Boolean values are typically represented with 0 for false and 1 for true. Examples of Boolean values include the following:

• (5 > 4)  True

• (10 = 10)  True

• (3 < 2) False

• (17 ≥ 17) True

• (“dog” = “cat”) False

• (“hello” ≠ “goodbye”) True

Boolean values are used in programming to perform calculations, make decisions, and control the flow of a program. For example, an if statement is a type of decision making statement that uses a Boolean expression to determine if a certain condition is true or false. If the condition is true, the program will execute the specified code, and if false, the program will skip the specified code. Boolean values are also used to perform calculations, such as in the AND, OR, and NOT logical operators, which are used to combine two or more conditions into one expression. For example, the AND operator would return true if both of the conditions are true and false if either of the conditions are false.

The solution is Option A.

The value of the missing length parallel to the side LN of the triangle is 44

If two triangles' corresponding angles are congruent and their corresponding sides are proportional, they are said to be similar triangles. In other words, similar triangles have the same shape but may or may not be the same size. The triangles are congruent if their corresponding sides are also of identical length.

Corresponding sides of similar triangles are in the same ratio. The ratio of area of similar triangles is the same as the ratio of the square of any pair of their corresponding sides

Given data ,

Let the first triangle be represented as ΔLMN

Let the second triangle be represented ΔVUN

The triangles LMN and VUN are similar

The measure of side LV = x

The measure of side LN = 11 + x

So , the corresponding sides of the similar triangles are in ratio

MU / UN = LV / VN

24 / 8 = x / 11

On simplifying the equation , we get

3 = x / 11

Multiply by 11 on both sides of the equation , we get

x = 33

Now , the measure of side LN = x + 11

The measure of side LN = 33 + 11 = 44

Hence , the measure of side LN is 44

What are similar triangles?

If the respective angles are congruent and the corresponding sides are proportional, two triangles are said to be similar. To put it another way, comparable triangles are similar in shape but not necessarily in size. In addition, the triangles are congruent if their corresponding sides are of identical length.

As it we know that for the two triangles to be similar triangles, the ratio of their corresponding sides should be the same.

DC/RD = DB/SD

∠R = ∠C = 68°

To calculate y, we use the sum() function with an argument of x < 5 to count the number of entries in x that are strictly less than 5. To calculate z, we use the sum() function with an argument of (x > -5) & (x < 5) to count the number of entries in x that are both greater than -5 and less than 5.

y = sum(x < 5)

z = sum((x > -5) & (x < 5))

y = sum(x < 5)

 = sum(TRUE, FALSE, FALSE, TRUE, FALSE, FALSE, TRUE, FALSE, TRUE, TRUE, TRUE, FALSE)

 = 5

z = sum((x > -5) & (x < 5))

 = sum(TRUE, FALSE, FALSE, TRUE, FALSE, FALSE, TRUE, FALSE, TRUE, FALSE, TRUE, FALSE)

 = 4

The first variable, y, is the number of entries of x that are strictly less than 5. To calculate y, we can use the sum() function with an argument of x < 5. This will count the number of entries in x that are less than 5. For example, if

x <- c(-5, 7, 9, 3, 14, 9, 5, 10, 2, -2, 0, 12), then y will be equal to 6 because there are 6 entries in x that are strictly less than 5.

The second variable, z, is the number of entries of x that are strictly between -5 and 5. To calculate z, we can use the sum() function with an argument of (x > -5) & (x < 5). This will count the number of entries in x that are both greater than -5 and less than 5. For our example, z will be equal to 4 because there are 4 entries in x that are strictly between -5 and 5.

Calculating the mean -

By averaging the squared deviations of each integer from the mean, you may get the variance before calculating the standard deviation.

Calculating the Standard deviation -

The solution set of the linear equation 2x - t.6.t-12 = 0 can be represented parametrically as x = t + 6.

A linear equation is an algebraic equation of the form y=mx+b. m is the slope and b is the y-intercept. The above is sometimes called a "linear equation in two variables" where y and x are variables.

The equation 2x - t.6.t-12 = 0 is a linear equation in the variable x and can be solved by isolating x to one side of the equation. To do this, first distribute t on the right side of the equation, giving 2x - 6t^2 + 12 = 0. Then add 6t^2 - 12 to both sides of the equation to get 2x = 6t^2 - 12. Finally, divide both sides of the equation by 2 to get x = 3t^2 - 6. This is a parametric representation of the solution set of linear equations. x is a function of parameter t. The solution is given by x = 3t^2 - 6.

The Mean is 350 and Median is 383.3

The first step in calculating the mean of grouped data is to establish the midpoint (also known as a class mark) of each interval or class. The frequencies of the relevant classes must then be multiplied by these midpoints. The mean value is determined by dividing the total number of values by the sum of the products.
