Answer:
B and D
Step-by-step explanation:
Given
![\frac{x+8}{x^2-2x-24}](https://tex.z-dn.net/?f=%5Cfrac%7Bx%2B8%7D%7Bx%5E2-2x-24%7D)
The denominator of the rational function cannot be zero as this would make it undefined. Equating the denominator to zero and solving gives the values that x cannot be.
Solve x² - 2x - 24 = 0, that is
(x - 6)(x + 4) = 0
Equate each factor to zero and solve for x
x - 6 = 0 ⇒ x = 6 → B
x + 4 = 0 ⇒ x = - 4 → D
Answer:
C
Step-by-step explanation:
3-2a<7
= -2a<7-3
=-2a<4
=-2a/-2<4\-2
=a<-2
