Question

If the perimeter of the

rectangle is 36 inches,
what is the value of x?
X-3
7x+5

Answer 1

x = 2

Explanation:

To find the value of x, we simply need to use the know values for the lengths, widths, and perimeter of the rectangle.

The formula for the perimeter of a rectangle is as follows:

P = 2L + 2W

Where P is the perimeter, L is the length, and W is the width.

Let L = 7x + 5 and W = x - 3

Now, we will simply plug our values into the formula and solve for x.

P = 2L + 2W

36 = 2 ( 7x + 5 ) + 2 ( x - 3 )

36 = 14x + 10 + 2x + -6

36 = 16x + 4

32 = 16x

2 = x

Thus, we have found the value of x to be 2.

Cheers.
