...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 ... 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
