50 is the number because it is a great number to compare it to.
The equation will simplify to a linear equation in n, which can be solved to find n.
n² +6n +8 = (n -2)(n -9) . . . . . . we assume this is your intent
n² +6n +8 = n² -11n +18 . . . . . . expand the right side
17n = 10 . . . . . . . . . . . . . . . . . . . add 11n -8 -n² to both sides
n = 10/17 . . . . . . . . . . divide by the coefficient of n
The number that makes the equation true is n = 10/17.

Answer: A) not periodic</h3>
Explanation:
Plot all of the data points on the same xy grid as shown below.
I used GeoGebra to make the diagram.
The points seem to be randomly scattered about without any apparent pattern (though there might be some symmetry going on). The data does <u>not</u> seem to be periodic.
Periodic data repeats itself at some point in time, for example like a waveform pattern, which unfortunately these data points don't reflect.
Ok I don’t use this to answer math questions
But you could use
