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

(3) agree
