Final answer:
Matrices with dimensions 3 x n can be multiplied to Matrix A with dimensions 1 x 3.
Step-by-step explanation:
To multiply a matrix and a vector, the number of columns in the matrix must be equal to the number of elements in the vector. In this case, Matrix A has dimensions 1 x 3, so the matrix that can be multiplied to it must have dimensions 3 x n, where n can be any positive integer.
For example, matrices with dimensions 3 x 1, 3 x 2, 3 x 3, etc. can be multiplied to Matrix A.
Therefore, the following matrices can be multiplied to Matrix A:
- Matrix with dimensions 3 x 1
- Matrix with dimensions 3 x 2
- Matrix with dimensions 3 x 3
- And so on...
