The length of side AB can be found using the distance formula:
d = √((x2 -x1)^2 +(y2 -y1)^2)
d = √((6 -(-6))^2 +(1 -6)^2) = √(144 +25) = 13
The sum of the side lengths is then ...
13 +7 +12 +12 = 44 . . . units perimeter

B. 3x⁷ + 7x⁴ - 2x + 7
Step-by-step explanation:
(3x⁷ + 8x⁴ + 7) - (x⁴ - 2x)
= 3x⁷ + 8x⁴ - x⁴ - 2x + 7
= 3x⁷ + 7x⁴ - 2x + 7
