For what values of x is the rational expression below undefined?
check all that apply.
x+8/x^2-2x-24
a. -6
b. -8
c. 8
d. 6
e. 4
f. -4

The correct options are D and F.

Step-by-step explanation:

The given expression is

The given expression is undefined if the value of denominator is equal to 0.

Equate the denominator value equal to 0.

The middle term can be written as -6x+4x.

Equate each factor equal to 0.

Therefore the given expression is undefined at x=6 and x=-4. Options D and F are correct.

answer: the angel abc is 30°,and the abc is a triangle where the angel bac is 90°

so ac is the half of 24=12ft,and from the pythagorean theorem we find ba

ba=√bc^2-ac^2=√576-144=√432=12√3ft

so bac is 12+12√3=12(1+√3)ft
