PLEASE HELP ME i will be marking brainliest if correct

765.85

Step-by-step explanation:

70% of 425 is 297.5

297.5 + 425 = 722.5

6% of 722.5 is 43.35

thus it is $765.85

If its simplified it would either be $765 or $766 depending if you want to round the decimal to the closest tenth or ones, or you dont neeed the decimal

this doesn't make sense lol

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
