Good morning ☕️

Step-by-step explanation:

-7x + 5 = 8x - 25

then

25 + 5 = 8x + 7x

then

Step-by-step explanation:

Given equation:

To find the value of 'x', take the terms of 'x' to one side and the constants to the other side:

Subtracting '' to both side:

Subtracting '' both side:

42

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
