I found: $C=A+B=(5i-j-3k)m$

You can add together the corresponding components to get:
$C=[(3+2)i+(-4+3)j+(4-7)k]m=$
$=(5i-j-3k)m$

Given the displacement vectors A= (3i – 4j + 4k)mA= (3i – 4j + 4k)m, and B= (2i + 3j – 7k)mB= (2i + 3j – 7k)m, how do you find the magnitudes of the vectors C= A+BC= A+B?
