Answer:
7(13a+4c)
Step-by-step explanation:
hi! let's find the GCF of 91 and 28 since a and c are separate variables. this is 7, since 91/7 is 13 and 28/7 is 4. we can take this out of the parentheses like this:
7(13a+4c)
this is basically like reverse distribution. if you distribute the 7 into the parentheses, you will get the original unfactored expression.
hope this helps!
