Answer:

X=15

Step-by-step explanation:

Ignore the increase for equasion. This is factored in but irellevent. Orignal x value is 13, but increases to 15, and orignal x value is not needed for this equasion. (its there to confuse you)

L+L+W+W=66.

(w+3) +(w+3) +w +w = 66

(4xw) + 3 +3= 66

4 x w = 66 -3 -3

4 x w =60

60/4= 15.

L= 15+ 3 =18

W = 15.

W + W + L + L

15 + 15 + 18 +18 =66

Draw 4 squares. The perimeter is 10 because the width is 4 and the length is 1. So 4 x 2 is 8 and 1 x 2 is 2. And 8 + 2 = 10.

The dimensions of a rectangular building are given as a length of 12x + 24 feet and a width of 20x - 10 feet. Write the expressi

Ray Of Light [21]

<h3>The expression that represents the area of the building, in terms of x is:</h3>

$Area = 240x^2 +360x - 240$

Solution:

Given that,

Dimensions of rectangular building:

Length = 12x + 24 feet

Width = 20x - 10 feet

The area of rectangle is given as:

$Area\ of\ rectangle = length \times width$

Substituting the values we get,

$Area\ of\ rectangle = (12x+24) \times (20x-10)$

Multiply both

$Area = 12x\times \:20x+12x\left(-10\right)+24\times \:20x+24\left(-10\right)\\\\Area = 240x^2 -120x + 480x -240\\\\Area = 240x^2 +360x - 240$

Thus the expression that represents the area of the building, in terms of x is found
