<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>
The perimeter of the hall is the sum of its side lengths.
The perimeter of the museum exhibit hall is 240 feet
<h3>How to determine the perimeter</h3>
From the question, we understand that the shape of the museum exhibit hall is a regular octagon
The perimeter of a regular octagon is:
p = 8l
Where l represents the side length of the octagon
So, we have:
p = 8 * 30 feet
Evaluate the product
p = 240 feet
Hence, the perimeter of the exhibit hall is 240 feet

The left side -0.77777777 does not equal to the right side -10.8, which means that the given statement is false so it is false
Best of luck
hope i helped :)
3:40
1:13
it would be 13.3 repeated but since you round to the nearest dollar it would be 13. All I did was divide 40 by 3.
