It is all the way simplfyed all the way, I hope that that answers your question☻
Answer: 475.59 meters .
Step-by-step explanation:
The correct equation is the following:
For this exercise you need to use the Quadratic formula:

In this case you can identify that the values of "a", "b" and "c" are:

Now you must substitute these values into the Quadratic formula and then evaluate. You get:

Choose the positive one and round it to the nearest hundreth:

Yintercept is the point where the line crosses the y axis and where x=0
(x,y)
yintercept at y=b is
(0,b)
Great job! you didn't include the rectangle! no one can answer this question! you're the best!
