    Single Vectors

    Use the rectangular prism to determine a single vector equivalent to each of the following vector combinations:

    Can you check my work please?

    1) HE - GA + FC = HC
    2) EA + HE - HC - CA = 0 vector
    3) AE + AD + AE=AG
    4) -AE + DA = HA
    5) AB + BC + CG = AG

    1) HE - GA + FC = HC ... I get AC
    2) EA + HE - HC - CA = 0 vector ... agree
    3) AE + AD + AE=AG ... 2AE + AD ? check the problem statement again
    4) -AE + DA = HA ... agree
    5) AB + BC + CG = AG ... agree
    ...

    Hi Skeeter! Thanks for the input.
    Corrections:
    3) AB + AD + AE = AG .. is this correct?

    Also, how did you get 1) as AC? I'm having trouble seeing that as the answer

    (1) HE - GA + FC =

    HE + AG + FC =

    DA + AG + FC =

    DG + FC =

    AF + FC = AC
