handwritten solution please for part a b c

Extracted text: P = (A,0, 0) P2 = (0, B,0) P3 = (0,0, C) a) Find the equation of the plane formed by the three points. b) Find a point that lies in this plane (which is not P1, P2 or P3) c) Together with the origin, the points form a figure. This has a uniform mass density. Calculate the mass of the figure using a triple integral. d) Calculate the distance from the origin to the plane found in problem (a) e) Check the answer in problem (c) by calculating the volume with the formula
