point a is the center of the circle that passes through points e, f, and g and the center of the circle that passes through points x, y, and z.

a; x = 0.5

step-by-step explanation:

-10x = -5

x = 0.5

hello from mrbilldoesmath!

answer:

25x^2 + 90x + 84

discussion:

mn(x) = m(n(x)) = m( 5x + 9) =

(5x + 9)^2 + 3 =>

25x^2 + 90x + 9^2 + 3 =

25x^2 + 90x + 84                 (as 9^2 = 9*9 = 81)

which is the second choice

mrb
