To use the distributive property to remove the parentheses in the expression \( (w + 10) \cdot 12 \), you multiply each term inside the parentheses by 12.
Here's how it works:
\[ (w + 10) \cdot 12 = w \cdot 12 + 10 \cdot 12 \]
Now perform the multiplication:
\[ = 12w + 120 \]
So, the expression without parentheses is:
\[ 12w + 120 \]
