ANSWER


<8,4> \bullet< - 3,5> = - 4

EXPLANATION

The dot product of two vectors:


< a,b >

and


< c,d>

is


< a,b > \bullet< c,d> = ac + bd

The given vectors are:


<8,4>

and


< - 3,5>

The dot product of these vectors is


<8,4> \bullet< - 3,5> = 8 * - 3 + 4 * 5


<8,4> \bullet< - 3,5> = - 24 + 20


<8,4> \bullet< - 3,5> = - 4
