Question

Consider the expression 63 + 81.

Answer 1

Answer:

You can use distributed property and GCF to find an equivalent expression because the GCF of both numbers is in the expression the GCF is what  you multiply with to get the first whole number then the second (63 and 81) the GCF of 63 and 81 is 9. That gives us a clue for the expression or the first factor. You can check if you are correct by evaluating the expression and if your expression has an equivalent product to 63+81 then you are correct.

Step-by-step explanation:

I got it right on edgenuity the answer above me is incorrect I tried it.

Answer 2

Ab+ac=a(b+c)
find a which is the GCF

63=3*3*7
81=3*3*3*3
GCF=3*3=9

9(7)+9(9)=9(7+9) is an equivilent expression
you can check by evaluating
