    1. The problem statement, all variables and given/known data

    Find the (a) x, (b) y, and (c) z components of the sum of the displacements and whose components (in meters, m) along the three axes are cx = 7.9, cy = -4.0, cz = -6.2; dx = 4.5, dy = -1.5, dz = 3.3.

    2. Relevant equations

    I dont know.

    3. The attempt at a solution

    No idea how to even begin this one... WileyPlus gave me a hint, but this hint is pretty much useless.

    I didn't wait until the last minute to do these problems, its just that this is the last one on Wiley that i need to do to get above a 9/10...

    Looks like you are adding 2 vectors C and D using unit vector notation. Are you familiar with representing a vector A like this: A = axi + byj + cz k?
