Answer:

sum of vector A, b and C = -2i + j + 5k

Step-by-step explanation:

the vectors i,j,k will be sum together like this

Sum = vector A+ vector B+ vector C

= (-3i -2j +7k ) + (1i+ 3j + 3k)+ (-5k)

= (-3+1)i + (-2+3)j + [7+3+(-5)]k

= (-2)i + (1 ) j + (5)k

= 2i + j + 5k

vector i will be added i, j to j and k to k
