The problem asks to find the inverses of the given 3x3 matrices. We need to calculate the inverse for each matrix listed in the image:

1. Matrix A: 3 & 0 & 1 \\ 2 & 5 & 1 \\ -1 & 0 & 2 \end{bmatrix}$$
2. Matrix B: 1 & 4 & 2 \\ 1 & 0 & 2 \\ 2 & 1 & 4 \end{bmatrix}$$
3. Matrix C: 1 & 1 & 2 \\ 1 & 2 & 3 \\ 1 & 3 & 2 \end{bmatrix}$$
4. Matrix D: 2 & -1 & 3 \\ -4 & 3 & -2 \\ 1 & -1 & 1 \end{bmatrix}$$
5. Matrix E: 3 & 5 & 2 \\ 5 & 7 & 4 \\ 0 & 1 & 6 \end{bmatrix}$$
6. Matrix F: 2 & -1 & 3 \\ -4 & 3 & -2 \\ 1 & -1 & 1 \end{bmatrix}$$
7. Matrix K: 2 & 3 & 1 \\ 0 & -3 & -2 \\ 5 & -1 & 4 \end{bmatrix}$$
8. Matrix L: 2 & 5 & 4 \\ -1 & 6 & 0 \\ 8 & 9 & 3 \end{bmatrix}$$
9. Matrix M: 3 & 0 & 11 \\ 2 & 5 & 1 \\ -1 & 0 & 2 \end{bmatrix}$$

To find the inverse of a matrix $A$, we use the formula:

$A^{-1} = \frac{1}{\text{det}(A)} \cdot \text{adj}(A)$

where $\text{det}(A)$ is the determinant of $A$ and $\text{adj}(A)$ is the adjugate of $A$.

I will start calculating the inverses one by one. Let's begin with Matrix A.The inverse of Matrix A is:
