You can factor this by taking out the GCF (greatest common factor).

In the expression, the greatest common factor between the two terms is 5.

Take out 5:

5(2b + 5)

No. So, your answer is D. 5(2b + 5).

What is 8 groups of0.32?
Lelechka [254]
Okay! In order to find 8 groups of .32 you'd simply divide them. So:

[.32 ÷ 8] = .04

To check you multiply:

[8 x .04] = .32.

The answer is .04
