Question
Determine whether each statement is true or false.$$\left|\begin{array}{rrr}2 & 6 & 4 \\0 & 2 & 8 \\4 & 0 & 10\end{array}\right|=2\left|\begin{array}{lll}1 & 3 & 2 \\0 & 1 & 4 \\2 & 0 & 5\end{array}\right|$$
Step 1
The determinant of a 3x3 matrix can be calculated as follows: $$\left|\begin{array}{rrr} a & b & c \\ d & e & f \\ g & h & i \end{array}\right|=a\left|\begin{array}{rr} e & f \\ h & i \end{array}\right|-b\left|\begin{array}{rr} d & f \\ g & Show more…

Real Numbers and Their Properties
Decide whether each statement is true or false. If false, tell why. $$\left[\begin{array}{rrr}{2} & {4} & {-1} \\ {3} & {7} & {5} \\ {0} & {0} & {0}\end{array}\right]=\left[\begin{array}{lll}{2} & {4} & {-1} \\ {3} & {7} & {5}\end{array}\right]$$
