Answer:
Diagram 1
Step-by-step explanation:
This diagram does not represent a function because the x value 6 is outputting 2 different y values, 4 and 6. This goes directly against the rules of a function.
We know that we can do
ab+ac=a(b+c)
so find common factor
factor them
27a=a times 3 times 3 times 3
21=3 times 7
common factor=3
3=a
27a/3=9a
21/3=7
so now we have
(3)9a+(3)7=3(9a+7)
