Determine if these matrices are inverses by calculating AB: matrix 1matrix 2 matrix 3 c11 = ⇒ 1 c12 = ⇒ 0 c21 = ⇒ 0 c22 = ⇒ 1 So the matrices inverses of one another. Now calculate BA: matrix 4 Find d11 = d12 = d21 = d22 =

part 1 answer = 8

part 2 answer = 72

step-by-step explanation:

part 1 explanation = add all of the numbers, then divide by how many numbers you have. so, 200/25 = 8.

part 2 explanation = not gonna lie, this is hard to explain, so just google how to do it.
