Select the correct answer.

Simplify the following expression.

[tex]\[
\frac{18x-108}{6x-54}
\][/tex]

A. [tex]\(\frac{3z-18}{x-9}\)[/tex]

B. [tex]\(\frac{z-6}{3x-27}\)[/tex]

C. [tex]\(\frac{3z-6}{x-9}\)[/tex]

D. [tex]\(\frac{x-18}{x-9}\)[/tex]



Answer :

Let's simplify the given expression step by step:

[tex]\[ \frac{18x - 108}{6x - 54} \][/tex]

First, factor out the common factors in the numerator and the denominator.

Step 1: Factor the numerator

The numerator is:

[tex]\[ 18x - 108 \][/tex]

We can factor out an 18 from both terms:

[tex]\[ 18x - 108 = 18(x - 6) \][/tex]

Step 2: Factor the denominator

The denominator is:

[tex]\[ 6x - 54 \][/tex]

We can factor out a 6 from both terms:

[tex]\[ 6x - 54 = 6(x - 9) \][/tex]

Step 3: Rewrite the original expression with the factored forms

Now we substitute the factored forms back into the expression:

[tex]\[ \frac{18(x - 6)}{6(x - 9)} \][/tex]

Step 4: Simplify the expression

We can simplify this expression by canceling out the common factor of 6:

[tex]\[ \frac{18(x - 6)}{6(x - 9)} = \frac{18}{6} \cdot \frac{(x - 6)}{(x - 9)} \][/tex]

Since [tex]\(\frac{18}{6} = 3\)[/tex], the expression simplifies to:

[tex]\[ 3 \cdot \frac{(x - 6)}{(x - 9)} = \frac{3(x - 6)}{x - 9} \][/tex]

Let's compare this simplified expression to the given options:

A. [tex]\(\frac{3x - 18}{x - 9}\)[/tex]

B. [tex]\(\frac{x - 6}{3x - 27}\)[/tex]

C. [tex]\(\frac{3x - 6}{x - 9}\)[/tex]

D. [tex]\(\frac{x - 18}{x - 9}\)[/tex]

None of the provided options match exactly with our simplified expression [tex]\(\frac{3(x - 6)}{x - 9}\)[/tex]:

Therefore, based on the simplification, none of the given options A, B, C, or D are the correct simplified version of the expression. The correct answer is none of the provided options.
