If the matrix \( A=\left[\begin{array}{ccc}-1 & 2 & 3 \\ -5 & 8 & -2 \\ 0 & 1 & -3\end{array}\right] \) then the negative of
\( \mathrm{P} \)
W.
\( 5 A \) is equal to
(1) \( \left[\begin{array}{ccc}5 & -10 & -15 \\ 25 & -40 & 10 \\ 0 & -5 & 15\end{array}\right] \)
(2) \( \left[\begin{array}{ccc}-5 & 10 & 15 \\ -25 & 40 & -10 \\ 0 & 5 & -15\end{array}\right] \)
(3) \( \left[\begin{array}{ccc}-5 & 10 & 15 \\ -25 & -40 & 10 \\ 0 & -5 & 15\end{array}\right] \)
(4) \( \left[\begin{array}{ccc}5 & -10 & -15 \\ 25 & 40 & 10 \\ 0 & 5 & 15\end{array}\right] \)
