Essentially, you must multiply 22 by 400. You get 8800 km apart for your answer.
Answer with Step-by-step explanation:
We are given that
A and B are matrix.
A.We know that for two square matrix A and B
Then, 
Therefore, it is true.
B. det A is the product of diagonal entries in A.
It is not true for all matrix.It is true for upper triangular matrix.
Hence, it is false.
C.

When is a factor of the characteristics polynomial of A then -5 is an eigenvalue of A not 5.
Hence, it is false.
D.An elementary row operation on A does not change the determinant.
It is true because when an elementary operation applied then the value of matrix A does not change.
It’s 22 (add 6 after every term)
When you're evaluating P(n, k), you are essentially saying there are n objects and you will need to arrange them in k spaces.
This is essentially the same as:

, which follows the formula:

If you're dividing by 4!, you are evaluating P(6, 2)
