A. dilation by a factor of 7
B. reflection about the line =
C. translation by 5 units to the left on the x-axis
D. rotation by 180°

B

Step-by-step explanation:because I got it correct

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

p.s.   i'll be on vacation from friday, dec 22 to jan 2, 2019. have a great new year!

it would rotate about 180 degrees.
