Here it is given that the width is x ft and total length of the fence is 2400 ft .
Let the length be y ft
So we have

Let A represents area, and area is the product of length and width .
So we get

Substituting the value of y, we will get

Second part
The area is maximum at the vertex, and vertex is

And

And that's the required dimensions .
Answer:
Step-by-step explanation:
x = (0.5,0)
y= (0,-3)
slope = 2
Answer: A. 3/5
Step-by-step explanation:
Count all the add numbers in 1-10 then add the 4 and you get
6/10
Simply and you get 3/5
Answer:
slope= 11
Step-by-step explanation:
(12,23) = (x1,y1)
(14,45) = (x2,y2)
Now,
slope(m)= (y2-y1)/(x2-x1)
=(45-23)/(14-12)
=22/2
=11
Answer: 8x−3
Step-by-step explanation:
Let's simplify step-by-step.
7−x−−5x−10+4x
=7+−x+5x+−10+4x
Combine Like Terms:
=7+−x+5x+−10+4x
=(−x+5x+4x)+(7+−10)
=8x+−3
