Is 9 a factor of 56a+12b

To determine if 9 is a factor of 56a + 12b, we need to find the remainder when dividing 56a + 12b by 9. If the remainder is 0, then 9 is a factor.

To simplify the expression, let's factor out 4 from both terms:

56a + 12b = 4(14a + 3b)

Now, let's test the factorization by dividing 14a + 3b by 9:

(14a + 3b) / 9

The remainder cannot be determined without knowing the values of a and b.

Therefore, we cannot determine whether 9 is a factor of 56a + 12b without knowing the specific values of a and b.
