slope:

do you mean add both of the equations together

because if you do the answer is 10x-5

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

mrb

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

cross multiplying, we get :

⇒ (3) × (5) = (9) × (x)

⇒ 15 = 9x

i those same problems in math and dont know how to do them
