Answer:
[tex]18[/tex]Explanation:
Here, we want to find the given expression
We start by finding the dot product of u and w
Mathematically, we have it that:
[tex]u.w\text{ = 1\lparen9\rparen + \lparen6\rparen\lparen-2\rparen = 9-12 = -3}[/tex]For v and w, we have it that:
[tex](5\times3)+(-3\times-2)\text{ = 15 +6 = 21}[/tex]Now, we have the sum of the two as:
[tex]-3\text{ + 21 = 18}[/tex]
