The answe would be 300 because, the perimeter of the windows is 12, then you have to multiply 25 to 12 then bam you get 300, yay!
Circumference = pi * diameter = 12pi ft or 37.7 ft

EXPLANATION
The given polynomial function is
![f(x) =2{x}^{3} + 3 {x}^{2} - 9x](https://tex.z-dn.net/?f=f%28x%29%20%3D2%7Bx%7D%5E%7B3%7D%20%20%2B%203%20%7Bx%7D%5E%7B2%7D%20%20-%209x)
To find the zeros, we equate the function to zero.
![2{x}^{3} + 3 {x}^{2} - 9x = 0](https://tex.z-dn.net/?f=2%7Bx%7D%5E%7B3%7D%20%20%2B%203%20%7Bx%7D%5E%7B2%7D%20%20-%209x%20%3D%200)
Factor x,
![x(2 {x}^{2} + 3x - 9) = 0](https://tex.z-dn.net/?f=x%282%20%7Bx%7D%5E%7B2%7D%20%20%2B%203x%20-%209%29%20%3D%200)
Split the middle term,
![x(2 {x}^{2} + 6x - 3x - 9) = 0](https://tex.z-dn.net/?f=x%282%20%7Bx%7D%5E%7B2%7D%20%20%2B%206x%20-%203x%20-%209%29%20%3D%200)
![x(2x(x + 3) - 3(x + 3) = 0](https://tex.z-dn.net/?f=x%282x%28x%20%2B%203%29%20%20-%203%28x%20%2B%203%29%20%3D%200)
![x(2x - 3)(x + 3) = 0](https://tex.z-dn.net/?f=x%282x%20%20-%203%29%28x%20%2B%203%29%20%3D%200)

Answer:
you would add 1 5/8
the 5/8 added to the 3/8 makes one
add that one with the other one which gives you 2
then add 3 and 2 and you get.....
Voila! 5
have a great day
