Question

a square scrapbooking page has a perimeter of (8x+20) inches.what is the length of one side of the scrapbooking?

Answer 1

One side of the scrapbooking is (8x+20)/4= 2x+5 inches.

Answer 2

`(2x+5)in`

Explanation:

we know that

The perimeter of a square is equal to

`P=4b`

where

b is the length side of the square

In this problem we have

`P=(8x+20) in`

so

`4b=(8x+20)`

solve for
`b`

Divided by
`4` both sides

`4b/4=(8x+20)/4`

`b=(2x+5)in`
