Nina believes that this expression is equivalent to dividing 12 by one less than x. Do your results from and (b) support this assertion? Explain. 12x-12/x^2 -1

its d. the first coordintaes are 10,32

step-by-step explanation:

a is the right answer

6/20

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
