Answer: 1920
Step-by-step explanation:
26/3 (improper fraction) 8.667
It is clear that (AB) is a median, and it is obvious that the angle is 90, thus it is an altitude and a perpendicular bisector

4(2)+2(1)^2-(1)^3 (^ just means to the power of "exponent")
8+2-1=9
The answer is this :) hope I helped
