See a solution process below:

Explanation:

The variable $t$ $t$ is not use in the expression in the problem therefore we can ignore it in this problem.

To evaluate $\sqrt{s} + | r |$ $sqrt(s) +abs(r)$ we need to substitute:
- $- 3$ $color(red)(-3)$ for each occurrence of $r$ $color(red)(r)$
- $4$ $color(blue)(4)$ for each occurrence of $s$ $color(blue)(s)$

$\sqrt{s} + | r |$ $sqrt(color(blue)(s)) + abs(color(red)(r))$ becomes:

$\sqrt{4} + | - 3 | \Rightarrow 2 + 3 \Rightarrow 5$ $sqrt(color(blue)(4)) + abs(color(red)(-3)) => 2 + 3 => 5$

$5$ $5$

Explanation:

$substitute the given values into the expression$ $"substitute the given values into the expression"$

$\sqrt{4} + | - 3 | = 2 + 3 = 5$ $sqrtcolor(red)(4)+|color(blue)(-3)|=2+3=5$

$note that the absolute value always returns a positive$ $"note that the absolute value always returns a positive"$
$value$ $"value"$
