The area of the shape as a sum is 2x^2 + 5x + 2.

The area of the shape as a product is (x+2) (2x+1).

What is area of a shape?

A figure surrounded by a barrier is referred to as a shape. Numerous things in shapes like square, rectangle, round, etc. are all around us.

The space around by a shape's perimeter or boundary is known as its area. Using particular mathematical methods, we may determine the area of shape for various geometric shapes.

Area as a sum

For this, we will simply add all the values given in the figure

⇒ x^2 + x^2 + x + x + x + x + x + 1 + 1

⇒ 2x^2 + 5x + 2

So, the area of the shape as a sum is 2x^2 + 5x + 2.

Area as a product

The shape given is a rectangle

Area of a rectangle is length * width

Now, the length is x+2 and the width is 2x+1

So, the area is

⇒(x+2) (2x+1)

So, the area of the shape as a product is (x+2) (2x+1).

Hence, the area of the shape as a sum and as a product are obtained.

The integers of a coordinate grid are used to find points. Each point on a graph may be specified by an ordered pair of numbers called an x-coordinate and a y-coordinate, respectively.

An ordered list's pairings are indicated by parentheses (x, y) (x,y). beginning place is at (0,0). Remember that when writing coordinates, there is usually no space after the comma. The co-ordinates in graphs are the cartesian coordinate points which enables us to exactly trace the specific point on a graph. There are 4 quadrants in a graph namely first second 3rd and 4th. When we have data about X&Y coordinate of each point those points can be traced on the graph on their respective axis. For example, x,y is equal to 2, 5 lies on the first quadrant since both the values are positive.

Two parallel lines called the x axis and the y axis are employed for graph or plot points. The x axis is on the horizontal number line, while the y axis is on the vertical line. The positive and negative axes of the x axis are arranged to the right and left of the origin, respectively.

The following format is employed to plot a point's coordinates: (x, y). As is evident, the x-coordinate is frequently placed first. For example, we have determined the x and y coordinates for the respective points B and D in the diagram we have been using. Point B's x-coordinate is 100.

Any position on the plane may have its x- and y-coordinates established using its horizontal and vertical distances from the origin. In essence, what we do when we sketch a point is the complete antithesis of what we do here.

Our x-coordinate is as follows:

Positive if it's in the appropriate area of our plane.

If it is on the left side of our plot, it is not ideal.

If it is on the x-axis, then it is 0.

Our y-coordinate is as follows:

If it is in the top part of our plot, it is a good indicator.

If it is in the bottom part of our plot, it is not good.

The formula of the nth term in the arithmetic sequence is a(n) = 3 + (n-1)9.

An arithmetic sequence is a sequence of numbers in which each term after the first is obtained by adding a fixed constant, called the common difference, to the preceding term.

The sequence can be represented by the general term an = a1 + (n-1)d, where a1 is the first term and d is the common difference

In an arithmetic sequence, the difference between consecutive terms is constant. Therefore, if a(1) = 3 and a(2) = 12, the common difference (d) is 12 - 3 = 9.

The nth term of an arithmetic sequence is given by the formula:

a(n) = a(1) + (n-1)d

where:

a(n) is the nth term of the sequence

a(1) is the first term of the sequence

d is the common difference

n is the position of the term in the sequence

So, for the given sequence, the nth term a(n) of the arithmetic sequence is:

a(n) = a(1) + (n-1)d = 3 + (n-1)9

This means that the nth term of the arithmetic sequence is found by adding the common difference (9) to the first term (3), and then multiplying the result by (n-1) which indicates the position of the term in the sequence.

Therefore, a(n) = 3 + (n-1)9 is the formula of the nth term in the arithmetic sequence.

Factorization is a mathematical process that is applied to split a number, an expression, matrix etc. into the product of factors such that when we multiplied these factors again we get the original one. We have, an equation is x² - 9x + 18 = 0 --(*) and we have to factorize it. Steps to factorize the quadratic equation, ax² + bx + c = 0, are :

Now, comparing the equation (*) with standard equation we get, a = 1 , b = -9 , c = 18.

So, Split the number 9, into 6 and 3

=> x² - 9x + 18

=> x² - 6x - 3x + 18

=> (x² - 6x) - (3x - 18) [ grouping]

=> x( x - 6) - 3( x-6) [ factors of group ]

=> (x- 3)(x- 6)

so, x² - 9x + 18 = (x- 3)(x- 6) = 0 helps to get the solution of it (x- 3)(x- 6) = 0 => x = 6,3
