Answer:
Hi there!
Your answer is:
the number is 68
Step-by-step explanation:
(18-n) /2 = -25
×2
(18-n) = -50
-18
-n = -68
/-1
n= 68
Plug it back in!
(18-68) /2 = -25 ???
-50/2 = -25 ✓✓✓
Hope this helps
We know the perimeter formula would be 1200=2x+2y. And the area will be A=x*y
We can to take the derivative of the area formula to find where it is a max but we must first substitute something in from the first formula so we only have one variable.
1200-2x=2y
600-x=y
A=(x)*(600-x)
A=600x-x^2
Now we take the derivative:
A'=600-2x (set equal to 0 and solve)
0=600-2x
2x=600
x=300
Then when we plug this into the perimeter formula, we can solve for y
1200=2x+2y
1200=2(300)+2y
1200=600+2y
600=2y
y=300
So both the length and width are 300 yards, and the area would be 90,000 square yards
