Hello there! Can you help me solve a problem? Thanks!
![### Matrix Computation Exercise
Compute each matrix sum or product if it is defined. If an expression is undefined, explain why.
Let the matrices be defined as follows:
\[ A = \begin{bmatrix} 2 & 0 & -2 \\ 3 & -6 & 3 \end{bmatrix}, \]
\[ B = \begin{bmatrix} 7 & -4 & 2 \\ 2 & -3 & -3 \end{bmatrix}, \]
\[ C = \begin{bmatrix} 2 & 3 \\ -2 & 2 \end{bmatrix}, \]
\[ D = \begin{bmatrix} 3 & 5 \\ -2 & 3 \end{bmatrix}, \]
\[ E = \begin{bmatrix} -5 \\ 4 \end{bmatrix}. \]
Expressions to compute:
- \( A + 3B \)
- \( 4C - 2E \)
- \( DB \)
- \( EB \)
**Note:** Check the dimensions of matrices involved in each operation to determine if the operation is defined.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fe00cebfb-aec4-474d-8979-79a2d105b819%2Ff35f2b65-ae27-4de1-ab90-5f86266ed184%2Fbz6x5l9_processed.png&w=3840&q=75)
