Answer:

$\frac{x+8}{x+2}$

Step-by-step explanation:

First we need to factorize the top and the bottom of the fraction:

$\frac{x^{2}+11x+24 }{x^{2}+5x+6 }$ = $\frac{(x+8)(x+3)}{(x+2)(x+3)}$

The we cancel out the common factor:

$\frac{x+8}{x+2}$ And that is our final answer.

X^2-12x-9=0
Add 9 to both sides
x^2-12x=9
Add (b/2)^2 to both sides
x^2-12x+36=45
Factor
(x-6)^2=45
So C is the answer

The confidence interval would be (0.122, 0.278).

We first find our z-score. We want a 95% confidence interval:

0.95/2 = 0.475

Looking this up in the z-table, (http://www.statisticshowto.com/tables/z-table/) we see the z-score is 1.96.

The formula we will use is:

$p \pm z\sqrt{\frac{p(1-p)}{n}}$

In this problem, p = 20/100 = 0.2, and n=100:

$0.2 \pm 1.96\sqrt{\frac{(0.2)(0.8)}{100}}
\\
\\0.2\pm 0.0784
\\
\\(0.2-0.0784, 0.2+0.0784)
\\
\\(0.1216,0.2784)$
