Answer:
4(-14z + 7)
Step-by-step explanation:
This expression is equivalent because if you distribute the 4 into the parenthesis, the same expression of -56z + 28 will be formed.
To find other expressions, find a common factor between the two numbers. For instance, a number that could replace the four outside of the parenthesis is 7; 56 divided by 7 is 8 and 28 divided by 7 is 4.
Hope this helps!
