Write your answer as a product with a whole number greater than 1.

This is 7th grade Algebra

Answer 1

6(9r - 7)

Explanation:

Think: what's the largest factor shared by 54 and 42?

54 = 6·9 and 42 = 6·7

That largest common factor is 6.

Then 54r - 42 = 6(9r - 7)

Answer 2

6(9r-7)

Explanation:

54r–42

Both 54 and 43 can be divided by 6

54/6 =9 and 42/6 =7

6*9r - 6*7

Factor out the 6

6(9r-7)
