If the perimeter of a square is 88 cm, find the length of its diagonal. Give in simplest radical form where possible.

22

Step-by-step explanation:

A square has 4 equal diagonals

And the perimeter of a square is 4L(length)

So the equation will be

=>Perimeter (P) =4L(length)

=>88=4L

=>88=4L

4. 4

=>the 4 will divide the 88 to get 22

=>L=22cm

You can consider lost yards as negative, and gaines yards as positive. So, if they lost 9 yards and then gained 9 yards, the expression is

-9+9=0

This means that the team is exactly where it started (which maked sense, because they lost exactly as much as they gained.

If they gained first and lost then, it wouldn't change a thing: you'd have

9-9=0

and so the team is always where it started.
