Here's my work. Hope it helps.
Answer:
4x^2 + 12x + 9
Step-by-step explanation:
(2x + 3)^2
it is in the form of (a + b)^2
(a + b)^2 = a^2 + 2*a*b + b^2
(2x + 3)^2
(2x)^2 + 2*2x*3 + (3)^2
4x^2 + 12x + 9
Answer:
The shortest total length of fence with which this can be done is 40m^2
Step-by-step explanation:
Lets say that your area has width
and length
. Since you want to divided it into 3 equal areas by fences there would be 4 lengths and the area and perimeter would be given by the following equations.
![3200 = w*l](https://tex.z-dn.net/?f=3200%20%3D%20%20w%2Al)
Perimeter = ![P = 4l+2w = 4l + \frac{2*3200}{l}](https://tex.z-dn.net/?f=P%20%3D%20%204l%2B2w%20%3D%204l%20%2B%20%5Cfrac%7B2%2A3200%7D%7Bl%7D)
We want to optimize the perimeter so
![P'(l) = 4-\frac{6400}{l^2} = 0](https://tex.z-dn.net/?f=P%27%28l%29%20%3D%204-%5Cfrac%7B6400%7D%7Bl%5E2%7D%20%3D%200)
Solving for
we get
![l = 40.](https://tex.z-dn.net/?f=l%20%3D%2040.)
Since
and
then ![w = 3200/40 = 80](https://tex.z-dn.net/?f=w%20%3D%203200%2F40%20%20%3D%2080)
