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:
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)
