You can turn this into an algebraic equation by changing the equation to -12 + x = -20. Our goal is to solve for x. This can be done by adding 12 to both sides. This gives us x = -8.

-12 + (-8) does equal -20.

Answer:

Square

Step-by-step explanation:

The length of AB is (a+b)-a = b. The length of BC is b-0 = b. So, adjacent sides are the same length. AB has a constant y-value, so is horizontal. BC has a constant x-value, so is vertical.

A figure with horizontal and vertical sides of the same length is a square.

201.64 + x^ = 595.36
x^ = 393.72
