[-2 0 -18][-10 -28 -4] Thank you for your help!!! God Bless and Happy Holidays!!!Answer by Jk22(389)   (Show Source): You can put this solution on YOUR website!since it is the multiplication of a 2x3 times 3x2 matrices, the result should be 2x2, hence A or C. The elem. 11 is -2-3*6=-20, the element 12 is 4+16+24=44, hence the solution is : A.
