Given three vectors A =3i -j +3k , B = -i + 2j -k and C = -3i +5j -3k

Find (A + B) · C



A + B = (3i - j +3k) + (-i +2j -k) = (2i + j +2k)
(A + B) *C = (2i + j + 2k) * (-3i + 5j - 3k) = -6 +5 -6 = 5

Nice work!

Your score is 4/5

Though you got your workings right. Your final arithmetic was an error. The answer is -7

Well done!
