Answer :
Answer:
2 x 5
Step-by-step 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
Final answer:
The sum of two 2 x 5 matrices A and B is also a 2 x 5 matrix as matrix addition is done element-wise and requires matrices to have the same dimensions.
Explanation:
When adding two matrices, such as matrix A and matrix B, the dimensionality of the resulting matrix will be the same as that of the individual matrices. Provided that both matrices A and B have dimensions of 2 x 5, their sum, A + B, will also result in a 2 x 5 matrix. This is because matrix addition is defined element-wise, meaning each corresponding entry of the matrices is added together, and thus the size of the matrices must be identical.
