Answer:
B)
Step-by-step explanation:
If two square matrix, with same dimensions, are inverse of one another, their product will always be the identity matrix with the same dimensions.
The matrix A and B are 2x2, so the result of the product A * B is a 2x2 identity matrix, that is represented as follows:
I = [1 0 ; 0 1]
(First line: 1 0, second line: 0 1)
So the correct option is B)
Answer:
-6 on top and 11 on bottom -6/11
Step-by-step explanation:
The perimeter is the sum of all of the sides.
3x + 2 + x + 13 + 3x + 8 + 2 + x + 5
Combine like terms:
8x + 30
So the perimeter is 8x + 30
