Answer 1

$-8.8s-20$

This is the expression for a square's perimeter.

We want to know the expression for the square's side.

We know all 4 sides of the square is equal.

Let one side length be x, so the perimeter is basically 4 times of that. THus, we can write:

4x = -8.8s - 20

If we divide by 4 all over, we get x, the side length. Let's do this:

$\frac{-8.8s-20}{4}=-\frac{8.8s}{4}-\frac{20}{4}=-2.2s-5$

Side length is:

-2.2s - 5
