  1. Nice question, and I could see your diagram.

    Several ways to do this, here is what I thought:

    easy to get the equation of BD : y = -x + 4
    and the equation of AQ = (1/2)x
    so for the intersection:
    (1/2)x = -x + 4
    x = -2x + 8
    3x=8
    x = 8/3

    so if we consider AB as the base and 8/3 as the height,
    area = (1/2)(4)(8/3) = 16/3

    If "u = (2,2,-1)", "v = (3,-1,0)" and "w = (1,7,8)", verify that "u (dot) (v + w) = u (dot) v + u (dot) w". My work: LHS: u (dot) (v + w) = (2,2,-1) (dot) (4,6,8) = [(2,2,-1) (dot) (3,-1,0)] + [(2,2,-1) (dot) (1,7,8)] = [u (dot)
