Answer:
5.99 feet.
Step-by-step explanation:
If the radius of the base of a right cylinder is r and its length is l, then the volume of the cylinder will be
Now, it is given that the volume(V) of the cylindrical tank is 2279.64 cubic feet and radius(r) of its base is 11 feet.
Therefore, the equation for getting the length(l) is
⇒ feet.
So, the length of the tank is 5.99 feet. (Answer)

Answer:
To do this, you need to multiply out the expressions. This is a bit tedious, but remember like FOIL for binomials, for these trinomials you must multiply each term. If you need a step-by-step, I'd be happy to provide it. Let me know.
Once you have simplified the expression, you get
-x-9/2x-4
But, the problem stipulates that a must equal 1. We can equivalently factor out the negative sign and put it on the denominator with no change to write
x+9/-(2x-4) = x+9/-2x+4
So, seeing where each coefficient corresponds between the two expressions, you get a = 1, b = 9, c = –2, and d = 4.
