Problem 4a: 

 
problem 4a
 

checkAnswer:

ad4a
 
 

Problem 5a: 

 
problem 5a
 

checkAnswer:

Since the degree is the sum of the variable exponents and it looks like we have a 2 and a 3 as our exponents, the degree would have to be 2 + 3 = 5.
 
 

Problem 5b: 

 
-8
 

checkAnswer:

Since this is a constant term, it's degree is 0.
 
 

Problem 6a: 

 
problem 6a
 

checkAnswer:

Since the degree of the polynomial is the highest degree of all the terms, it looks like the degree is 5.

Since there are two terms, this is a binomial.
 
 

Problem 6b: 

 
problem 6b
 

checkAnswer:

Since the degree of the polynomial is the highest degree of all the terms, it looks like the degree is 3.

Since there is one term, this is a monomial.
 
 

Problem 6c: 

 
problem 6c
 

checkAnswer:

Since the degree of the polynomial is the highest degree of all the terms, it looks like the degree is 2.

Since there are two terms, this is a trinomial.
