Answer:
C. 20, 40, 4, 56
Step-by-step explanation:
C = 3.14 x D or C = 2 x 3.14 x R
So, C = 2 x 3.14 x 20
The answer is 40pi.
Introduction,3 body paragraph, and one conclusion paragraph(restate the question for the intro)
Y=(x+9)(x-3)+c
∵(-3,-36)lies on it.
-36=(-3+9)(-3-3)+c
-36=(-6)(-6)+c
-36=36+c
c=-36-36=-72
y=(x-9)(x+3)-72
y=x^2+3x-9x-27-72
y=x^2-6x-99
It should be C. Equilateral triangles
