The degree of a polynomial is the value of the highest exponent a variable is raised to (i.e., the degree of the equation

is 2, since the highest exponent of a variable is 2.
If we apply this concept to your list of polynomials, we see that polynomial A and polynomial D both have

terms, so they are both fifth-degree polynomials. However, your answer must also be a trinomial (a polynomial with three terms.) If we look at polynomials A and D, we see that only polynomial A has three terms, so that must be the answer!

Substituting y=x-6 into the equation,
3x + 2(x-6) = 3x + 2x - 12 = 5x - 12
5x - 12 = 8
5x = 20
x = 4
Answer:
46 with a remainder of .5
To solve this, you first subtract 60 by 18 to get 42
You then divide this by 2 to get 21
So, it'll take 21 minutes
