Question

Consider the expression 63 + 81. How can you use the distributive property and the GCF to find an equivalent expression? Explain how you can check your answer.

Answer 1

Answer:

63+81=9(7+9)

You can check your answer by:

9(7+9)

9(7+ )=63

9( +9)=81

Multiplying the GCF by every term in the parenthesis.

Answer 2

Answer:

The GCF of 63 and 81 is 9, so you can use that as the factor outside of the parentheses. Divide both numbers by 9 and write the sum as 9(7 + 9). You can check that the sum 63 + 81 is the same as the product 9(7 +9).
