Answer:
x≠-1,1
Step-by-step explanation:
f(g(x)) is a composition where g(x) is is substituted for x in f(x).
Recall, f(x) is 2/x. So we write 2/|x|-1. This places x in the denominator and 0 cannot be in the denominator x. Any value of x that makes the denominator 0 will not be in the domain.
|x|-1=0
|x|=1
x=1,-1
The sum of the first n natural numbers and 0=
n*(n+1)/2

Answer:
The vale of x=4
Step-by-step explanation:
We know that the sum of angles of a triangle = 180°
Given
Thus, the equation becomes
(3x+13) + (8x+14) + 109° = 180°
11x + 27 + 109° = 180°
11x = 180°- 109° - 27
11x = 44
x = 4
Thus, the vale of x=4
