Final answer:
Reflecting shape A in the x-axis results in a new shape that is a mirror image of the original shape, but flipped upside down.
Step-by-step explanation:
Reflecting shape A in the x-axis results in a new shape that is a mirror image of the original shape, but flipped upside down. All points on the original shape are reflected across the x-axis to form the new shape. For example, if the original shape had a point (2, 3), the reflected shape would have the point (2, -3).
