To expand \( 5(y + 2) \) using the distributive property, you multiply 5 by each term inside the parentheses:
\[ 5(y + 2) = 5 \cdot y + 5 \cdot 2 \]
Now, calculating each term:
\[ 5 \cdot y = 5y \] \[ 5 \cdot 2 = 10 \]
Putting it all together:
\[ 5(y + 2) = 5y + 10 \]
So, the expanded expression is:
\[ 5y + 10 \]
