which expression shows 50 + 30 written as a product of two factors?

To express \(50 + 30\) as a product of two factors, we first simplify it:

\[
50 + 30 = 80
\]

Now, we want to see which of the options gives us \(80\) when evaluated:

A - \(5(10 + 3) = 5 \times 13 = 65\)

B - \(10(5 + 3) = 10 \times 8 = 80\)

C - \(10(5 + 2) = 10 \times 7 = 70\)

D - \(5(10 + 7) = 5 \times 17 = 85\)

The only option that evaluates to \(80\) is:

**B - \(10(5 + 3)\)**.
