The position of the trout now relative to the surface is -17 feet. Therefore, Denis is wrong.
<h3>What is an expression?</h3>
It should be noted that a expression shows the relationship between the variables.
From the information, a trout was swimming 9 feet below the surface of a lake and it drove down 8 more feet to search for food.
The position will be the addition of the feets. This will be:
= -9 + (-8)
= -9 - 8
= -17 feet
The position is -17 feet.

Answer:
6√3 square units
Step-by-step explanation:
The ratios of side lengths in a 30°-60°-90° triangle are 1 : √3 : 2. Using this fact, we can find the lengths of the orthogonal sides of the triangle to be ...
3(2/√3) = 2√3 . . . . side AB in the attached figure
and
2·3 = 6 . . . . . . . . . . side AC in the attached figure
Then the area of the triangle is ...
A = 1/2bh
A = 1/2(6)(2√3) = 6√3 . . . . square units
