Answer:
A = 12 ft
Step-by-step explanation:
Perimeter ( of SQUARE) B = 64
then each side = 64/4 = 16
AREA of SQUARE C = 400
side X side = 400
then side = sqrt 400
Now use Pyhtagorean Theorem to find leg of right triangle that is
side A Side B hypotenuse Side C
A^2 + 16^2 = (sqrt 400)^2
A^2 = 400 - 256
A^2 = 144 then A = 12 Ft
x = -3, y = -0.512
x = -1, y = -3.2
x = 0, y = -8
x = 2, y = -50
a=-5/2
-6a=-5-8a
-6a+8a=-5-8a+8a
2a=-5
