20. Use the remainder theorem and the factor theorem to determine whether (c + 5) is a factor of
(c4 + 7c3 + 6c2 – 18c + 10).
A. The remainder is 0 and, therefore, (c + 5) is a factor of (c4 + 7c3 + 6c2 – 18c + 10).
B. The remainder is 0 and, therefore, (c + 5) isn’t a factor of (c4 + 7c3 + 6c2 – 18c + 10).
C. The remainder isn’t 0 and, therefore, (c + 5) is a factor of (c4 + 7c3 + 6c2 – 18c + 10).
D. The remainder isn’t 0 and, therefore, (c + 5) isn’t a factor of (c4 + 7c3 + 6c2 – 18c + 10).

Your question are unclear to me. Online "^" is used to indicate an exponent, e.g., x^2 = x squared. Also some of questions are lacking adequate data.

Lastly, we do not do your work for you. Once you have attempted to answer your questions, we will be happy to give you feedback on your work. Although it might require more time and effort, you will learn more if you do your own work. Isn't that why you go to school?
