Answer 3

please apply this rule:
let's suppose that a matrix A is a (p*q) Matrix, namely A has p rows and q columns
and a matrix B is a (q*r) matrix, namely B has q rows and r columns, then the product matric C, namely C=a * B is a (p*r) Matrix, namely C has p rows and r columns

Answer 4

hint:
in your case A is a (2*3) matrix, and B is a (3*4) matrix, so what is C=A*B?

Answer 5

72?

Answer 6

would it be 2 times 4

Answer 7

hint:
please referring to the rule above, I have:
p=2, q=3 and r=4,
so C is a (2*4) matrix, so your answer is right!
congratulations!!
