Hi, I took the test and the correct answer is: The perimeter is the sum of the length of the sides. A square has four equal sides. The perimeter of a square is four times the side length.
Since we know x=6, replace all the x with 6 in the equation and then follow the PEMDAS rule. y= -2(6)^2 + 2(6) + 2 y= -2 (36) + 2 (6) + 2 y= -72 + 12 + 2 y= -60+2 y= -58
