4+x= 3(x + 2) - 2x I really don’t get how to this at all like I really don’t get it I need some help

no solution

Step-by-step explanation:

Given

4 + x = 3(x + 2) - 2x ← distribute and simplify right side

4 + x = 3x + 6 - 2x

4 + x = x + 6 ( subtract 4 from both sides )

x = x + 2 ( subtract x from both sides )

0 = 2 ← not possible

This indicates the equation has no solution

idk

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
