U = 6i – 10j<br> g= -81 – 11j<br> Find: -3u + 5g
VARVARA [1.3K]

Answer:

-3u + 5g =-58i -25j

Step-by-step explanation:

Given

u = 6i - 10j

g=-8i - 11j

Required

-3u + 5g

We have:

-3u + 5g

This gives:

-3u + 5g = -3(6i - 10j) + 5(-8i - 11j)

Open bracket

-3u + 5g = -18i + 30j - 40i - 55j

Collect like terms

-3u + 5g = -18i - 40i+ 30j  - 55j

-3u + 5g =-58i -25j
