Since the degree is the sum of the variable exponents and it looks like
we have a 7 and a 1 as our exponents, the degree would have to be 7
+ 1 = 8. 
Answer/Discussion
to 2a
Since the degree of the polynomial is the highest degree of all the
terms, it looks like the degree is 3.
Since there are two terms, this is a binomial. 
Answer/Discussion
to 2b
Since the degree of the polynomial is the highest degree of all the
terms, it looks like the degree is 1.
Since there is one term, this is a monomial. 
Answer/Discussion
to 2c
Since the degree of the polynomial is the highest degree of all the
terms, it looks like the degree is 2.
Since there are three terms, this is a trinomial.
