Answer:
42 - 12z
Step-by-step explanation:
We can find an equivalent expression by using distributive property
Distributive property: whenever there is a number outside of the parenthesis you multiply that number by whatever is in the parenthesis
So for -6(-7+2z) we would multiply the number outside of the parenthesis (-6) by what's inside of the parenthesis ( -7 and 2z )
-6 * -7 = 42
-6 * 2z = -12z
An equivalent expression would be 42 - 12z
