Answer

\begin{bmatrix} 11 & 35 \\ 8 & 0 \\ -9 & 7 \end{bmatrix}

Work Step by Step

$$ \begin{bmatrix} 5 & 2 \\ 0 & -4 \\ 1 & 6 \end{bmatrix} \times \begin{bmatrix} 3 & 7 \\ -2 & 0 \end{bmatrix} = \begin{bmatrix} (5\times3)+(2\times(-2)) & (5\times7)+(2\times0) \\ (0\times3)+(-4\times(-2)) & (0\times7)+(-4\times0) \\ (1\times3)+(6\times(-2)) & (1\times7)+(6\times0) \end{bmatrix} = \begin{bmatrix} 11 & 35 \\ 8 & 0 \\ -9 & 7 \end{bmatrix} $$
