What value of x makes
the equation below true? 2(x+5) =6x+2

Now,

2(x + 5) = 6x + 2

or, 2x + 10 = 6x + 2

or, 10 - 2 = 6x - 2x

or, 8 = 4x

◆ x = 2

I hope you understand...

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
