Answer 1

Both Alex and Anthony are incorrect. The product of -3 x 4 is -12.

Step-by-step explanation:

Both Alex and Anthony are incorrect. The product of -3 x 4 is actually -12. To understand why, we can use a number line. Starting from 0, we move 3 units to the left (since -3 means a negative value) and then multiply it by 4. Multiplying by 4 means adding 4 equal jumps to the left. So, we end up at -12. Therefore, the correct product is -12.
