Answer:

 

 
Problem 4a: 

 

 

Answer:

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 4b: 

 
-8
 

Answer:

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

 
 
Problem 5a: 

 

 

Answer:

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 5b: 

 

 

Answer:

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 5c: 

 

 

Answer:

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.
