Select the student who correctly subtracted the rational expressions. Emma:
1/X-1 - 3/(X-1)(x+3)= 1(X+3)+3/(x-1)(x+3)= x+6/(x-1)(x+3)
Steve:
1/x-1 - 3/(x-1)(x+3)= 1(x+3)-3/(x-1)(x+3)
Maria:
1/x-1 - 3/(x-1)(x+3)= -2/x+3
George:
1-3/x-1-x^2-2x+3= -2/-x^2-x+2

there will be 35 boys in each team. : )

.there can be infinite values of m and n that can satisfy the above equation. for each value of m of m or n. there maybe infinite sets of solution for the above

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
