Answer 4

what happens when we factor out an x?

ohh ok i got it. so it doesnt matter what order its in

Answer 6

nope; doesnt matter

Answer 7

\[3\times 7 = 7 \times 3\]
so
\[3 \times 7 + 7 \times 3 = 2\times 7 \times 3\]
in other words there is no difference between xy and yx so you can add them.
