Matrix A has 3 rows and 2 columns. Matrix multiplication AB cannot be done if matrix B hasa.2 rows and 1 columnb.2 rows and 3 columnsc.3 rows and 3 columnsd.2 rows and 4 columns

Which of the following is true for Matrix A that has 3 rows and 3 columns, Matrix B that has 3 rows and 3 columns?A. AB = BAB. A+B = B+ASelect an option Clear ResponseBoth A and BOnly AOnly BNone of the given options

Two matrices A and B are multiplied to get AB ifA.both are rectangularB.both have same orderC.no of columns of A is equal to columns of BD.no of rows of A is equal to no of columns of B

Consider a 3x3 matrix denoted by A with first row [-1  3  2], second row [0  4  1] and third row [1  2  5], and another 3x3 matrix, B, with first row [6  2  -1], second row [3  5  2] and third row [-2  -3  0]. The matrix 2A-5B is:a.First row [-3 -2 -5], second row [-1 -1 -8] and third row [2 1 0]b.First row [2 -4 0], second row [5 7 -2] and third row [1 1 0]c.First row [-32 -4 9], second row [-15 -17 -8] and third row [12 19 10]d.First row [11 -3 5], second row [-1 6 -7] and third row [1 0 -2]

If A = 2543 and 2A + B is a null matrix, then B is equal to :
