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

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

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