To expand \( \frac{2}{5}(-5c + 10) \), we will distribute \( \frac{2}{5} \) to both terms inside the parentheses:
\[
\frac{2}{5} \cdot (-5c) + \frac{2}{5} \cdot 10
\]
Calculating each term:
1. For \( \frac{2}{5} \cdot (-5c) \):
\[
\frac{2 \cdot (-5c)}{5} = -2c
\]
2. For \( \frac{2}{5} \cdot 10 \):
\[
\frac{2 \cdot 10}{5} = \frac{20}{5} = 4
\]
Now, combine the results:
\[
-2c + 4
\]
So the final expanded expression is:
\[
-2c + 4
\]
The correct response is:
**−2c + 4**
\[
\frac{2}{5} \cdot (-5c) + \frac{2}{5} \cdot 10
\]
