Answer:
16 feet of fencing
Step-by-step explanation:
This equation is essentially asking us the perimeter of the fence. If you add 5+3+5+3 you get the sum of 16
Why not? Because every math system you've ever worked with has obeyed these properties! You have never dealt with a system where a×b did not in fact equal b×a, for instance, or where (a×b)×c did not equal a×(b×c). Which is why the properties probably seem somewhat pointless to you. Don't worry about their "relevance" for now; just make sure you can keep the properties straight so you can pass the next test. The lesson below explains how I kept track of the properties.
Answer:
I think it will be combined and simplified
