Answer:

The least common denominator of the two rational expressions is $(x+2)^{2}\cdot (x+3)$ .

Step-by-step explanation:

Let be the following rational expressions:

$\frac{x^{3}}{x^{2}+4\cdot x + 4}, \frac{-9}{x^{2}+5\cdot x + 6}$

Then, we factor each denominator:

$\frac{x^{3}}{(x+2)^{2}}, \frac{-9}{(x+3)\cdot (x+2)}$

Now, we compare each denominator to find all missing binomials so that each expression may have a common denominator:

$\frac{x^{3}}{(x+2)^{2}} \rightarrow (x+3)$

$\frac{-9}{(x+3)\cdot (x+2)} \rightarrow (x+2)$

Hence, we conclude that least common denominator of the two rational expressions is $(x+2)^{2}\cdot (x+3)$ .

Answer: The value of the expression when $n=9$ is $22$

Step-by-step explanation:

In this case, you need to remember that:

1. Tthe word "less than" indicates a subtraction.

2. By definition, the "Difference" in the result of a subtraction.

3. The word "times" indicates multiplication,

Based on the information given above, you know that " Six times the difference of a number and five" can be expressed as:

$6(n-5)$

Then, "Two less than six times the difference of a number and five" can be represented with this expression:

$6(n-5)-2$

Now you can substitute $n=9$ into the expression and the evaluate in order to find the value of the expression. This is:

$6(9-5)-2=6(4)-2=24-2=22$
