Given f(x) = [(x^2 -2x -15)/x-5], notice it is a rational
function
But the numerator x^2 -2x -15 could be factored, which
yields
(x – 5)(x + 3)
Therefore f(x) = (x – 5)(x + 3)/ (x-5)
Cancelling x-5, f(x)
= x + 3
In this way, the f(x) is continuous at any point, and is
basically a line.

Answer:
x = 18
Step-by-step explanation:
Total interior angle of pentagon: 540 degrees
(3x + 23) + (9x - 6) + 95 + 90 + (7x - 4) = 540
19x + 23 - 6 + 95 + 90 - 4 = 540
19x + 17 + 95 + 90 - 4 = 540
19x + 13 + 185 = 540
19x + 198 = 540
19x = 342
x = 18
