Multiple Choice

Find the inverse of the matrix, if it exists
- $A = \left[ \begin{array} { r r } - 5 & - 5 \\ 2 & 2 \end{array} \right]$

A) A is not invertible
B)
$$\left[ \begin{array} { c c } \frac { 2 } { 21 } & \frac { 5 } { 21 } \\- \frac { 2 } { 21 } & - \frac { 5 } { 21 }\end{array} \right]$$
C)
$$\left[ \begin{array} { c c } - \frac { 2 } { 21 } & - \frac { 5 } { 21 } \\\frac { 2 } { 21 } & \frac { 5 } { 21 }\end{array} \right]$$
D)
$$\left[ \begin{array} { l } \frac { 2 } { 21 } - \frac { 5 } { 21 } \\\frac { 2 } { 21 } - \frac { 5 } { 21 }\end{array} \right]$$
