8 A = 2x2
Work out the value of A when x = 4

439400

step-by-step explanation:

130^2 = 16900

16900*26 = 439400

c - they will have the same distribution

step-by-step explanation:

this is the only one that could make sense. : )

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
