Step-by-step explanation:
D=9
A=pie*radius^2
=3.14*9/2*9/2
=63.58
=64
A is the correct answer
Or
Vertex = (-5,-4), y-intercept = (0,21), x-intercepts = (-7,0) and (-3,0), axis of
symmetry is x = -5
10x^3(8x^3+3x)
([10x^3 x 8x^3]+ [10x^3 x 3x])
80x^6+ 30x^4
•this is as simplified as it gets; it isn’t possible to add or subtract numbers with different exponents.

D because 3/4 is .75 so 7.75 divided by .75 equals 10.333333333333333
