Use Structure The area of a rectangular playground has been extended on one side.

The total area of the playground, in square

meters, can be written as 352 +22x.

Rewrite the expression to give a possible set

of dimensions for the playground,

The width and length of the rectangle are and , for , respectively.

Step-by-step explanation:

From Geometry, we remember that area of the rectangle () is defined by:

(1)

Where:

- Width.

- Length.

In addition, we know that area is described by a first-order polynomial:

(2)

Meaning that is the product of another first-order polynomial and a constant. That is:

 (3)

Now we determine the Great Common Divisor of 352 and 22:

The Great Common Divisor is 22.

Then, the area of the rectangle can be expressed by this expression:

(3b)

According to this, the width and length of the rectangle are and , for , respectively.

g(x) is the negative form of f(x)? because whenever its the negative form it reflects its self over the x axis. idk if this is right though.

step-by-step explanation:

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl
