Answer:
(A+B)(A+B)=A.A+B.A+A.B+B.B
Step-by-step explanation:
Given that matrices A and B are nxn matrices
We need to find (A+B)(A+B)
For understanding the multiplication of matrices let'take A is mxn and B is pxq matrices,we can multiple only when n=p,so our Ab matrices will be mxq.
We know that that in matrices AB is not equal to BA.
Now find
(A+B)(A+B)=A.A+B.A+A.B+B.B
So from we can say that (A+B)(A+B) is not equal to A.A+2B.A+B.B because AB is not equal to BA in matrices.
So (A+B)(A+B)=A.A+B.A+A.B+B.B

Answer:4 in each package
Step-by-step explanation:
By definition, an absolute frequency is the measure of how frequently an event occurs based on data from an experiment of survey.
This frequency is independent of what the other events in the experiment are and thus is termed absolute frequency.
Thus, for the given question, option B, absolute frequency is the correct option.
