the correct answer is the last option
Answer:
Result after multiplication of polynomial is: 
Degree of polynomial = 3
Step-by-step explanation:
The given polynomials are:

In order to multiply the given polynomials we have to work step by step. First of all the polynomials in the bracket will be multiplied and then their result will be multiplied with x.
So, multiplying the polynomials in round brackets first

Now multiplying with x

Degree of a polynomial is the highest exponent of variable in the polynomial.
In the acquired result, the highest exponent of x is 3 so the degree is 3.
Hence,
Result after multiplication of polynomial is: 
Degree of polynomial = 3
Total cost = 15*14 ( 0.89 + 2.99 ) + 2(15 + 14) 0.19 = $825.82
Yes because when you divide 4 by 2 you get 2 and when you divide 14 by 2 you get 7
