If 5 <2x+3<115<2x+3<115, is less than, 2, x, plus, 3, is less than, 11, what is the possible range of values of -4x-6−4x−6minus, 4, x, minus, 6?

only 10/60 isn't equivalent

hope this : )

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
