Answer
$\lt 20,2 \gt$
Work Step by Step
Our aims is to add two vectors , in order to this we will simply add add the vertical component together to get the vertical component of sum , and the horizontal components together to get the horizontal component of sum.
Thus, we have:
$u=\lt -2, 5 \gt $ and $v = \lt 4, 3 \gt $
Therefore,
$-2u+ 4 v = -2 \lt -2, 5 \gt + 4 \lt 4, 3 \gt \\= \lt 4+16,-10+12 \gt \\= \lt 20,2 \gt$
