For which rational expression is -5 an excluded value of x?
A) x-5/6
B) x+5/6
C) 6/x-5
D) 6/x+5

Respuesta :

Answer:

D

Step-by-step explanation:

An excluded value is any value of x that makes the denominator of the rational expression zero as this would make the expression undefined.

Consider expression D

[tex]\frac{6}{x+5}[/tex]

This will be undefined when

x + 5 = 0 ⇒ x = - 5 ← excluded value → D
