I believe its B
i hope this helps :)
Answer:
Step-by-step explanation:
According to the Polynomial Remainder Theorem, when dividing a polynomial P(<em>x</em>) by a binomial in the form (<em>x - </em>a), the remainder will be given by P(a).
We are given the polynomial:
And it is divided by the binomial:
The remainder is 21.
Rewriting the divisor yields:
So, <em>a</em> = -1.
Then by the PRT:
Simplify:
Solve for <em>k: </em>

It is 102.5. You made it kind of confusing at first by putting the divisor first in your question then putting your dividend, but I understand what you meant.
