Expand 5(y + 2) using the distributive property.

A. 6y + 7
B. 5y + 10
C. 5y + 2
D. 6y + 10

To expand 5(y + 2) using the distributive property, we distribute the 5 to both terms inside the parentheses.

5(y + 2) = 5y + 5(2)

Simplifying further:

5y + 10

Therefore, the expanded form is 5y + 10.

The correct option is B. 5y + 10.
