Answer:
B and D
Step-by-step explanation:
Given
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:
905.26
Step-by-step explanation:
905.255

Answer: 19
Step-by-step explanation:
The answer is 19 because, if n=5 then we have to divide 45 by 5. 45 divided by 5 equals 9. and to make sure we can multiply 9 and 5 and that equals 45. So now its saying what is 9 plus 10 and that equals 19. Just to make sure we can subtract 19 by 10 or 9 and if we do eitheer one they both equal 19.
