Sort each equation according to whether it has one solution, infinitely many solutions, or no solution. 5(x - 2) = 5x - 7
One Solution
Infinitely Many Solutions
No Solution
-30% - 4) = -3x + 12
4(x + 1) = 3x + 4
-2x - 3) = 2X-6
6(x+5) = 6x +11

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
