Isolate x by adding 8 to both sides.
3 = x/3
Then, multiply by 3 on both sides.
9 = x
To prove that this is right, you can imput 9 into the equation and it equals -5.
May I leave you to simplify the following values of probability?
(a) 512/1906.
(b) 808/1906.
(c) 775/1348.
(d) 24/808.
The volume of this box is indeed 84 in^3. What were you looking for beyond that?
Base: (7 in)(3 in) = 21 in^2
Height: 4 in
volume = (21 in^2)(4 in) = 84 in^3 (answer)

Answer:

Step-by-step explanation:
Let be x and y the length and width of the rectangular field, whose area and perimeter are, respectively:


Building cost is minimum when perimeter is minimum, then equation system must be reduced and critical values have to be found:


Then,


Now, critical values are determined by First and Second Derivative Tests:
FDT




(As length is a positive number)
SDT

(which means that critical point leads to a minimum).
Now, the value of the other variable is:


Lastly, the cost of building the fence is:
![C = 2 \cdot [\$ 3 + \$ 8 ]\cdot (14.142\,m)](https://tex.z-dn.net/?f=C%20%3D%202%20%5Ccdot%20%5B%5C%24%203%20%2B%20%5C%24%208%20%5D%5Ccdot%20%2814.142%5C%2Cm%29)
