Ryan, a consumer electronics salesperson, eams a base salary of \( \$ 1500 \) per month and a commission of \( 5 \% \) on the amount of sales he makes. One month Ryan received a \( \$ 1835 \) paycheck. Find the amount of his sales for the month. Ryan had sales of \( \$ \square \) for the month.

ii) \( x^{3}-2 x^{2}-(2 x-1)(x-2)=0 \)

Compute each sum below. If applicable, write your answer as a fraction. \( 2+2(-2)+2(-2)^{2}+\ldots+2(-2)^{7}=\square \) \( \sum_{k=1}^{9}\left(\frac{1}{3}\right)^{k}=\square \)

(116) \( 3(\sqrt{3}+\sqrt{6})^{2}-(\sqrt{14}+\sqrt{7})^{2}-6 \)

\( 117)(5 \sqrt{2}+3)(5 \sqrt{2}-3)-(14 \sqrt{3}-1)-7(\sqrt{1,5}-\sqrt{2})^{2} \).

Find a degree 3 polynomial with real coefficients having zeros 3 and \( 3 i \) and a lead coefficient of 1 . Write \( P \) in expanded form. \( P(x)=\square \)
