Answer to Problem 46RE

Solution: $-12$

Explanation of Solution

Determinant of matrix is given by:-

  $\left|\begin{array}{cc}\begin{array}{l}a\\ c\end{array}& \begin{array}{l}b\\ d\end{array}\end{array}\right|=ad-bc$

  $\left|\begin{array}{cc}\begin{array}{l}-4\\ 1\end{array}& \begin{array}{l}0\\ 3\end{array}\end{array}\right|=-4(3)-0(1)=-12$
