Well if we’re adding them all together 1.2+1.2+1.2+1.2+1.2= 6kg
The maximum area of the pen is the highest area the pen can have
The maximum area is 16200 square yards
Let the dimension be x and y.
So, the perimeter is given as:
Because it has one additional fence, the perimeter is calculated as:
Make y the subject
The area is calculated as:
Substitute
Expand
Differentiate
Set to 0
Rewrite as:
Divide both sides by 4
Substitute 90 for x in
Hence, the maximum area is 16200 square yards

Answer:
<h2>
X = 4.5</h2>
Step-by-step explanation:
So we have two equations.
y=35x+40
y=40x+17.5
We want to find the coordinates in which they intersect.
BUT They never intersect, They are parallel to each other leaving us with a
NO SOLUTION
When you are trying to solve for x you want to get rid of the y's and simply put on your paper: 35x+40 = 40x+17.5
Then you distribute, in which I am not going to show because that too many steps lol. But you'll get:
x=4.5
What is the formula for the area of a triangle? A = 1/2 bh, right? If we let b = the length of the base, then the height is b + 7, seven feet greater than the base. Put in the info we have. A = 1/2 bh 15 = 1/2 b(b+7) 30 = b2 + 7b 0 = b2 + 7b - 30 Since we can't factor the equation, it's time to pull out the old quadratic formula. x = -b + √(b2 - 4ac) / 2a = -7 + √49 - 4(1)(-30) / 2 = = -7 + √169 / 2 -7 +13 / 2 = 3 -7 - 13 / 2 = -10 We can't have a negative length, so our base is 3. This makes the height 10. Let's check. 1/2(3)(10) = 15. Good to go!
