12. Perform the indicated operation. \[ \left[\begin{array}{cc} -8 & 12 \\ -9 & -6 \\ 11 & -5 \end{array}\right]+\left[\begin{array}{ccc} 1 & 2 & 3 \\ 0 & 2 & -12 \end{array}\right] \] \( \left[\begin{array}{cc}-8 & 11 \\ -11 & -8 \\ 23 & -8\end{array}\right] \) \( \left[\begin{array}{cc}-7 & 12 \\ -7 & -4 \\ 14 & -17\end{array}\right] \) \( \left[\begin{array}{cc}-9 & 12 \\ -11 & -8 \\ 8 & 7\end{array}\right] \) \( \left[\begin{array}{cc}-8 & 13 \\ -7 & -4 \\ -1 & -2\end{array}\right] \) This operation cannot be performed with these matrices.

Step 1
The first matrix is a \(3 \times 2\) matrix: \[ \left[\begin{array}{cc} -8 & 12 \\ -9 & -6 \\ 11 & -5 \end{array}\right] \] The second matrix is a \(2 \times 3\) matrix: \[ \left[\begin{array}{ccc} 1 & 2 & 3 \\ 0 & 2 & -12 \end{array}\right] \] Show more…
