Answer:
7(a +6)
Step-by-step explanation:
7 is a factor of both terms, so we can factor that out.
42 +7a = 7·6 +7·a = 7(6 +a)
Answer:
7(6+a)
Step-by-step explanation:
When you are doing this, you have to first find a common factor. In this case it is 7 because 7*6=42 and 7*a=7a. So the common factor is 7 because it has it in both numbers when factoring. You then take the common factor out and see what is left.
So you the the 7 out and whats left is 6+a.
You then write this into an expression. 7(6+a)
