\(\begin{pmatrix} 16 & 36 \end{pmatrix}\)
\(\begin{pmatrix} 8 & 18 \end{pmatrix}\)
\(\begin{pmatrix} 8 & 0 \end{pmatrix}\)
\(\begin{pmatrix} 1 & 2 \end{pmatrix}\)
Correct answer is A
\(|Q| = \begin{vmatrix} -1 & -2 \\ 3 & 2 \end{vmatrix}\)
= \(-2 - (-6) = 4\)
\(4P = 4\begin{pmatrix} 4 & 9 \end{pmatrix}\)
= \(\begin{pmatrix} 16 & 36 \end{pmatrix}\)
