A square picture frame has a perimeter of (16x − 20) feet. Write an
expression that represents the side length of the picture frame (in
feet).
If (16x - 20) represents the perimeter, and we have a square, then each side is 1/4 of this....
So.....an expression for the side is
(16x - 20) * (1/4) =
(4x - 5 ) feet
4x -5,,,,,,,,,,,,,,,,,,,, yes!
