Step-by-step explanation:

$\frac{x + 4}{3 {x}^{2} - 12x - 96} = \frac{x + 4}{3( {x}^{2} - 4x - 32) } = \frac{x + 4}{3(x - 8)(x + 4)}$

$= \frac{1}{3(x - 8)} = \frac{1}{3x - 24}$

Alexxx [7]

Answer:

The answer is B

Step-by-step explanation:

Because A is incorrect because the -8.9 is in absolute value which mean it will be an 8.9 which is greater than 5.6

C is Incorrect because - 5.6 is not greater than the absolute value of -8.9 which is 8.9, as you can see is greater than -5.6

D is incorrect because the absolute value of 5.6 is still 5.6 and the absolute value of - 8.9 is 8.9 which is greater that 5.6

<h2>B is correct because the absolute value of -5.6 is 5.6 which makes it less than the absolute value of -8.9 because the absolute value is 8.9 which is greater than 5.6 .</h2>
