-8vecu = <8, -32>

Explanation:

We're given two vectors

vecu = <-1,4>

vecv = <3,-2>

and asked to find the value of -8vecu, so vector vecv I'm assuming is irrelevant..

Vector vecu multiplied by the scalar quantity -8 is thus

<-8(-1), -8(4)>

= color(blue)(ulbar(|stackrel(" ")(" "<8, -32>" ")|)
