Part C: Using the GCF you found in Part B, rewrite 72 + 81 as two factors. One factor is the GCF and the other is the sum of two numbers that do not have a common factor. Show your work. (4 points)

OpenStudy (elfynelfy12344):

Vocaloid (vocaloid):

ok, so we can factor out our GCF of 9

Vocaloid (vocaloid):

72 + 81 = 9(___ + ____) now, we use the distributive property to figure out what goes into the blanks

Vocaloid (vocaloid):

we take our original numbers, 72 and 81, and divide them by 9

Vocaloid (vocaloid):

what is 72/9 = ?

OpenStudy (elfynelfy12344):

8

Vocaloid (vocaloid):

OpenStudy (elfynelfy12344):
