The Determinant of a Square Matrix and Cramer's Rule
determine whether each statement is true or false. If the statement is false, make the necessary change(s) to produce a true statement. Only one $2 \times 2$ determinant is needed to evaluate $$ \left|\begin{array}{ccc}{2} & {3} & {-2} \\ {0} & {1} & {3} \\ {0} & {4} & {-1}\end{array}\right| $$
