Answer
$20$
Work Step by Step
Remainder Theorem:
If the polynomial $P(x)$ is divided by $x-c$ , then the remainder is the value $P(c)$ .
$\left.\begin{array}{l}
11 \ \lfloor \\ \\ \\ \end{array}\right.\begin{array}{rrrrr}
2 & -21 & 9 & -200 \\\hline
& 22 & 11 & 220 \\\hline
2 & 1 & 20 &|\ \ \ 20 \end{array}$
$R(x)=P(11)=20$
