Multiple Choice

Find the inverse, if it exists, for the matrix.
- $$\left[ \begin{array} { l l l } 7 & - 5 & 2 \\14 & - 9 & 4 \\7 & - 4 & 2\end{array} \right]$$

A) The inverse does not exist.
B)
$$\left[ \begin{array} { l l l } 7 & 14 & 7 \\- 5 & - 9 & - 4 \\2 & 4 & 2\end{array} \right]$$
C)
$$\left[ \begin{array} { l l l } \frac { 1 } { 7 } & \frac { 1 } { 7 } & - \frac { 5 } { 2 } \\\frac { 1 } { 2 } & \frac { 10 } { 9 } & \frac { 7 } { 4 } \\1 & - \frac { 1 } { 2 } & \frac { 1 } { 2 }\end{array} \right]$$
D)
$$\left[ \begin{array} { c c c } \frac { 1 } { 7 } & \frac { 1 } { 14 } & \frac { 1 } { 2 } \\\frac { 1 } { 14 } & - \frac { 1 } { 9 } & \frac { 1 } { 4 } \\\frac { 1 } { 7 } & - \frac { 1 } { 4 } & \frac { 1 } { 2 }\end{array} \right]$$
