Problem 2a: 

 
73,200,000
 

checkAnswer:

ad2a

 
 
Problem 3a: 

 
problem 3a
 

checkAnswer:
ad3a
 

 
Problem 4a: 

 
problem 4a
 

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 4b: 

 
-8
 

checkAnswer:

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

 
 
Problem 5a: 

 
problem 5a
 

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 5b: 

 
problem 5b
 

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 5c: 

 
problem 5c
 

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.

 
 
Problem 6a: 

 
problem 6a
 

checkAnswer:

ad6a

 
 
Problem 6b: 

 
problem 6b
 

checkAnswer:

ad6b

Problem 8a: 

 
problem 8a
 

checkAnswer:

ad8a

 
 
Problem 8b: 

 
problem 8b
 

checkAnswer:

Step 1: Set up the long division 

AND

Step 2: Divide 1st term of divisor by first term of dividend to get first term of the quotient

AND

Step 3:  Take the term found in step 1 and multiply it times the divisor

AND

Step 4:  Subtract this from the line above

AND

Step 5:  Repeat until done

AND

Step 6: Write out the answer.
