What we are doing here is algerba )which im not very good at), and it says to expand each expresstion 1) 4(2a - 1)
2) 7 ( c - 2)
3) 2(3 + 5b)
4) 5(2d + 3)

1)4(2a-1) you will multiply numbers in the bracket by 4 which will be equal to 8a-4

2)7(c-2) same applies as number one will give you 7c-14

4)2(3+5b) = 6+10b

4)5(2d +3 ) = 10d +15

c. (3,2,6) is the answer.

step-by-step explanation:

divide, then simplify your answer.

1. make -15.66 ÷   5.8 a fraction. then divide.

2. simplify.  

3. final answer.
