Answer:
If AB = BA = I, then B is inverse of A and vice-versa.
Step-by-step explanation:
Given: AB = BA = I
To find: The relation between matrix A and B.
If AB = BA = I, then B is called the inverse matrix of A and is denoted by
.
In that case, A is said to be invertible.
Also, if B is the inverse of A, then A is also the inverse of B.
Hence, the relation between A and B is that both are inverse of each other.
If you simplify 2xy+8x-8x-32 you get 2xy-32
Answer: LM = 23
Step-by-step explanation:
Solve the algebraic equations:
Line KN: (solve for x)

move the 3 to the other side with addition

divide by 14 to get x by itself

Now that we have x we can find line KL:

So we now know that KL is 23 units. And we know that KL = LM
