Answer:
Point D
Step-by-step explanation:
Point A is located at (2, 3) on the coordinate plane. Point A is reflected over the x-axis to form point B and over the y-axis to form point C. Then, point A is reflected over both axes to form point D.
8.4 x 10^2 (10 to the 2nd power) = 8.4 x 100 = 840
The answer is A. 840
B and C (I think they are the same)
