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]
