Question

If Matrix A has dimensions 2 x 4 and Matrix B has dimensions 1 x 4, can these matrices be multiplied?

YES OR NO

Answer 1

no

rows of first must match collumns of second

rows by collumns
2 by 4
1 by 4

2≠4

no

Answer 2

No, This matrices cannot be multiplied.

Explanation:

If Matrix A has dimensions 2 x 4 and Matrix B has dimensions 1 x 4.

Dimension of matrix A = 2 x 4

Dimension of matrix B = 1 x 4

Multiplication rule.

Two matrices can only be multiplied when row number of one matrix equal to column number of other matrix.

In this case only 4 is common but both of them are column numbers. So these matrices cannot be multiplied.

No, This matrices cannot be multiplied.
