Question 147699
Distributing is when you have an expression such as 3(2+5). You have to multiply both numbers inside the parentheses by the number outside the parentheses. so you get 6+15.  In 7+7y, they are just asking you to go backwards, factor it.  They both have 7, so the number seven will be outside of the parentheses. {{{7(what+who)}}}.  Then figure out 7 times what is seven. One, so {{{7(what+who)}}} becomes {{{7(1+who)}}}.  Then figure out 7 times who is 7y. You should get y. So {{{7(1+who)}}} becomes {{{7(1+y)}}}. You wanna check? Distribute by multiplying both numbers inside the parentheses by the number outside the parentheses.  Did you get 7+7y? Good.


so 7+7y factors as 7(1+y).
