Simplify
((-2)(-2))(2)+(4)(3)
The answer is 20.
Step-by-step explanation:
since all 4 sides are equal in length, the figure is a square.
let the length of the square be lm.
529 = l x l
l = 23m
perimeter = 23 x 4 = 92m

9x + 1 = 5x - 15
Subtract 1 from both sides.
9x = 5x - 16
Subtract 5x from both sides.
4x = -16
Divide both sides by 4.
x = -4
