y = 1
(0.4.1)
(0.8.1)
(1.0.4)
(1.0.8)

0.8

Step-by-step explanation:

y=1

1+3=4

-5x ÷5

4÷5 = 0.8

whats the question?

step-by-step explanation:

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
