I need help answer these questions. : (

16. (a.) -8x-24 (b.) 27+63y

Step-by-step explanation:

A.      -4 x 2x = -8x

-4 x 6 = -24

B. 9 x 3 = 27

9 x 7y = 63y

15. Her commission is $10.72.

16a.-8x-24

b.27+63y

Step-by-step explanation:

15. $134 multiplied by the 8% that she makes from commissions is 134x0.08=10.72

16a. Expand -4(2x+6)

-4 times 2x is -8x

-4 times 6 is -24

put them together and get -8x-24

b. Expand 9(3+7y)

9 times 3 is 27

coefficient of y is 9 times 7 which equals 63

put them together and get 27+63y
