GPT-4o mini · Answer

We will use the **distributive property** to simplify the expression $-3(2x + 7)$. The distributive property allows us to multiply each term inside the parentheses by $-3$. Thus, the expression can be simplified as follows: $$ -3(2x) - 3(7) = -6x - 21 $$ So the complete sentence would be: "We will use the **distributive property** to simplify this expression."
