Suzane can work 10 math problems in 15 minutes. How many can she work in an hour and a half? help

60 math problems

Step-by-step explanation:

15 minutes fits into an hour and a half (90 minutes) 6 times

So we simply multiply what she can do in 15 minutes (10 math problems) by 6

10 x 6 = 60

So Suzanne can do 60 math problems in an hour and a half

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
