C.$9

Step-by-step explanation:

We are given that the ratio of the number of cups of yellow paint to the number of cups of blue paint that Greg mixed to make a shade of green paint is 2:1

A.

Ratio of number of cups of yellow paint to the number of cups of blue paint=2:1

Number of cups of yellow paint =2

Number of blue paint=1

It means Greg will need  2 cups of yellow paint mixed with each cup of blue paint.

B.2 cup of yellow paint  need cup of blue paint =1

1 cup of yellow paint need cup of blue paint=

Hence, the number of blue cups is should Greg add to each cup of yellow paint to make the shade of green.

C.If Greg purchased number of cups of yellow paint =6

Cos of 6 cup=$54

Cost of each cup =$9

Hence, the unit price per cup of yellow paint is $9.

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
