Multiplying the matrices A and B would yield the following matrix:
| 1 0 |
| 0 1 |
A simple method would be using a calculator to solve for this. You can input the values of one matrix, and then the values of another matrix, then multiply them and it would yield the above result. As a rule of thumb, you make sure to only multiply similar matrices.

Answer:
Kathleen determines the four arithmetic means to be −2.8 , 1.4, 5.6, and 9.8.
Step-by-step explanation:
The overall interval is 14 -(-7) = 21 units in length. The four equally-spaced "means" divide the interval into 5 equal parts, each one of which is ...
21/5 = 4.2
The four means are ...
-7 +4.2 = -2.8
-2.8 +4.2 = 1.4
1.4 +4.2 = 5.6
5.6 +4.2 = 9.8
