Question

Suppose A and B are 2 x 5 matrices. Which of the following are the dimensions of the matrix A + B? 2 x 5 10 x 10 7 x 7 7 x 1

Answer 1

2 x 5

Explanation:

When we add matrices, the dimensions of the matrices being added must be the same

A and B are 2 x 5 matrices so they are both 2 x 5 matrices

The output or the sum is also a 2 x 5 matrix
