Answer 1

Answer:

6(9r-7)

Step-by-step 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)

Answer 2

Answer:

6(9r - 7)

Step-by-step 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)
