I was thinking that maybe the expression is to determine how long the red frame lies on the edge of the picture?

tkhunny · Answer

2x + 2(4) is the entire frame length.
2x + 2(4) - 6 is the red frame.

Why do you doubt?

I wasn't sure if I was right, and I have no idea where the 8 comes from. So I'm a little confused.

timmyk14 · Answer

Maybe 2x+8 is the entire picture length, and when you subtract 6 you have the length of the red frame? It makes sense, no?

timmyk14 · Answer

So...
Part A: The expression represents the length of the red frame that has been placed on the edge of the picture.
Part B: 2x+8 is the length of the picture itself.
Part C: The picture is a rectangle so 2x is multiplying one side by its parallel side. 
Am I right?
