You can solve this in two ways.
1. Graphical. Plot the graph for x between -5 and 1 (see attachement).
The vertex of the graph is the peak of the curve, which has the coordinates x=-2, y=-9.
2. Analytical. Calculate the derivative of the function f(x)

Solve the equation:

will give the solution x=-2.
Replace x=-2 in the f(x) function and you'll get the value of y:

You get the same answer: x=-2, y=-9
So the answer is

16n+8=4
16n=4-8
16n=-4
n=-4/16
n=-1/4.
5 can go into 20 numbers between 1-100 and 8 can go into 12 numbers between 1-100
Answer:
x = -14

If you had the hypotenuse and one of the legs you could subtract the to using Pythagorean theorem. you cant answer the question unless you have another leg or a degree or a right triangle. <span />
