Miranda Frost · Answer 1

Yes, the dimensions will be 2x2

Step-by-step explanation:

When multiplying matrices you have AxB by CxD. You can only multiply matrices if the inner number is the same.

Ex. 2x3 by 3x2 or QxD by DxW

The dimensions of the result will depend on the outer numbers.

Ex. 2x3 by 3x2 has a 2x2 result or QxD by DxW has a QxW result
