Which expression is the greatest common factor of the two addends in 18x + 30x2?

Step-by-step explanation:

I think common factors are

18 = 1 2 3 6 9 18

30 = 1 2 3 10 15 30

So highest common factor is 3

18x + 30x2

3x (6 + 10x)

to determine the unit cost your would divide the total cost by the number sold.

5 bagels for $3.60         $3.60/5 = $.72 each at value mart
