ANSWER

[tex]3[/tex]

EXPLANATION

The given expression is


[tex]3+11t-9u[/tex]

The question demands that, we find the value of the given expression when

[tex]t = 9 \: and \: u = 11[/tex]


This is a substitution problem, so we substitute the given values to obtain,


[tex]3+11(9)-9(11)[/tex]



This simplifies to,


[tex] = 3+99-99[/tex]

We evaluate to obtain,

[tex] = 3 + 0[/tex]

This will finally give us,

[tex] = 3[/tex]

The result of 3 + 11t - 9u when t = 9, and u = 11 is 3

The expression is given as:

3 + 11t - 9u

When t = 9, and u = 11.

The expression becomes

3 + 11t - 9u = 3 + 11 * 9 - 9 * 11

Evaluate the products

3 + 11t - 9u = 3 + 99 - 99

Evaluate the sum and difference

3 + 11t - 9u = 3

Hence, the result of 3 + 11t - 9u when t = 9, and u = 11 is 3
