Question

A rectangle has sides with length (x+3) and (x+4). Find the perimeter by adding binomials.

Answer 1

Well if \[P=2l+2w\] and lets just say \[(x+3)=l\] and \[(x+4)=w\] try to substitute in and see if you can do it!

Answer 2

Do you understand why you would substitute like that?

Answer 3

Yes(: how would I do it though?

Answer 4

So in the original equation, you'll substitute in length and width

Answer 5

It will look like this: \[P=2(x+3)+2(x+4)\] but I want you to try to figure out how to solve it! :)

Answer 6

Would it be 4x+14??
