2X2

Answer 1

You can multiply a \( 2 \times 3 \) matrix by a \( 3 \times n \) matrix, where \( n \) can be any integer.

From the options given, a \( 2 \times 12 \) matrix would be a valid multiplication partner for a \( 2 \times 3 \) matrix, because the inner dimensions match (3 in the first matrix and 3 in the second).

So, the correct response is:

**2X12**
