Step 1
Step 2: Evaluate det(A) The matrix A is given by: $$ A = \begin{vmatrix} -a & -b & -c \\ 2d & 2e & 2f \\ -3g & -3h & -3i \end{vmatrix} $$ We can use the property of determinants that states if a row (or column) of a matrix is multiplied by a scalar k, then the Show more…

Evaluate the following determinants and negative of determinants of order two: (a) $\left|\begin{array}{cc}2 & 5 \\ 3 & 6\end{array}\right|, \quad\left|\begin{array}{cc}3 & -6 \\ 1 & -4\end{array}\right|, \quad\left|\begin{array}{rr}-4 & -2 \\ 7 & -3\end{array}\right|$ (b) $-\left|\begin{array}{cc}6 & 4 \\ 7 & 5\end{array}\right|, \quad-\left|\begin{array}{rr}1 & -3 \\ 2 & 4\end{array}\right|, \quad-\left|\begin{array}{rr}8 & -3 \\ -6 & -2\end{array}\right|$
Let $A=\left[\begin{array}{lll}a & b & c \\ d & e & f \\ g & h & i\end{array}\right]$ and assume $\operatorname{det}(A)=-6 .$ Find $\operatorname{det}(B)$ $$B=\left[\begin{array}{ccc} -4 d & -4 e & -4 f \\ g+5 a & h+5 b & i+5 c \\ a & b & c \end{array}\right]$$
