What are the dimensions of the product?
2,4,-3
6,1,0
-3,2
-2,3
-8,5 1x2
2x2
3x2
3x3

answer:

2 x 2

step-by-step explanation:

recall that multiplication of two matrices a and b in the form "a x b", to be possible, the following must apply:   a has to be of dimension mxn

and b of dimension nxp, where you notice the repeated "n" value in the number of columns of matrix a that has to coincide with the number of rows of matrix b.

such product is a new matrix c whose dimension is mxp that is, a matrix of m rows and p columns)

in our case, matrix a is a matrix of 2 rows and 3 columns (therefore of dimension 2x3), while matrix b is contains 3 rows and 2 columns (therefore of dimension 3x2). we see that the value that needs to coincide is "3" (indicated in bold), and the resultant matrix product is going to a a new matrix of dimension given by the remaining values: 2x2.

correct answer is b. 27/8
