12g+21 equals to 3(4g+7) because you have to multiply 3 and 4g which will equal 12g and then multiply 3 and 7 which will equal 21.

So your final answer would be 12g+21 equals to 12g+21.

Hope it helps!!

Answer 2

These two expressions are equivalent, making this statement true.

When we distribute 3(4g + 7), we multiply 3 by both of the values inside the parenthesis to find that:

3(4g + 7) → 12g + 21

Because 12g + 21 = 12g + 21, these expressions are true.
