and b =
1 0
0 1
0 0

a. multiply a and b or explain why you cannot.
b. would you consider b to be an identity matrix for a? why or why not?
c. would you consider = 0

answer:

step-by-step explanation:

here, the total dishes = 10

dishes having meat = 3 ( chicken, meatloaf and hamburger )

=

=

=

⇒ option b is correct.
