Plz me get the right answer for these i hate math

C. y = 60x + 120

Step-by-step explanation:

The cost increases by $60 for every hour you rent, so '60x' represents this part of the equation.  Since it increases $60 for each hour, there is a flat rate of $120 to rent the limo since at the first hour, the cost is $180.  $180 - $60 = $120

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
