<span>In the function "y=x2-18x" the goal is to find the value of the letter x. We know that y equals x2-18x. First, recognize that x2 is the same thing as 2x. So changing the problem to "y=2x-18x". We can subtract 18x from 2x, which leaves us with -16x. Now the problem looks like this: y=-16x. In order to get x by itself, we will need to do the same thing to both sides of the equation. In this case, we want the answer to be x by itself, or (1x) which is the same thing. We divide both sides of the equation by (-16). We are left with the following: y/-16=x. Basically, in words, x equals y divided by negative 16.</span>

Answer:
486√3 ft² ≈ 841.8 ft²
Step-by-step explanation:
The area of a regular hexagon with side length s is ...
A = (3√3)/2s²
For the side length of 18 ft, the area is ...
A = (3√3)/2(18 ft)² = 486√3 ft² ≈ 841.8 ft²
