26. Reasoning Suppose the product of two matrices has dimensions 4 X 3. If one of the matrices in the multiplication has dimensions 4 X 5, what are the dimensions of the other matrix?
1 answer
The dimensions of the other matrix must be 5 X 3 in order for the product to have dimensions 4 X 3. In matrix multiplication, the number of columns in the first matrix must be equal to the number of rows in the second matrix in order for the multiplication to be possible.
