What is the perimeter of a square with side length 2x-3

Perimeter of a square: side length * 4, since squares have equal side lengths

Take 2x - 3 for the side length and plug it into the formula.

(2x - 3) * 4 can be rewritten as 4 (2x - 3)

Distribute 4 inside the parentheses.

8x - 12 = perimeter of the square

4 (2x-3) or (2x+-3) + (2x+-3) + (2x+-3) + (2x+-3) = 8x-12
