Answer: Alright, let's see here...
1 - binomial
2 - trinomial
3 - monomial
4 - none of the above
5 - trinomial
6 - binomial
The difference between these terms is that a monomial has one term, bi has two, tri has three. Once you understand how these equations are built then they become relatively easy to see and distinguish from one another. Now math is not my strong suite so 4 could also be a trinomial but I'm pretty sure it's none of the above. Good luck!
7 - 12 fry my brain too much to do.
