Determine whether A B is defined If it is defined express t

Determine whether A + B is defined. If it is defined, express the result as a single matrix; if it is not, say A = [0 4 -4 1 5 1], B = [9 1 0 -6 3 -2] Select the correct choice below and, if necessary, fill in the answer box to complete your choice. The expression A + B is defined. A + B = The expression A + B is not defined.

Solution

Matrix A and B both are 2 x 3 order.

These can be added. So A + B is defined

A + B =   [9      5        -4]

               [-5    8        -1]

This is the required matrix
