Answer:

option A

Step-by-step explanation:

$\frac{x+ 3}{12x} \ \cdot \ \frac{4x}{x^2 +x - 6}\\\\= \frac{x+ 3}{12x} \ \cdot\ \frac{4x}{x^2 +3x - 2x - 6}\\\\= \frac{x+ 3}{12x} \cdot \frac{4x}{x(x + 3) -2(x+3)}\\\\= \frac{x+ 3}{12x} \cdot \frac{4x}{(x + 3)(x -2)}\\\\= \frac{1}{12x} \ \cdot \ \frac{4x}{(x - 2)} \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \\\\= \frac{1}{3} \ \cdot \ \frac{1}{(x - 2)}\\\\= \frac{1}{3(x - 2) }$

2 less then 3 times a number is 9

Masteriza [31]

$\huge\boxed{\text{As an expression:}\ 3x-2=9}$

$\huge\boxed{\text{Solved for x:}\ x=\frac{11}{3}}$

Let's start with " $3$ times a number". We will use $x$ to represent the number. $3x$

" $2$ less than" is next. $-2$

Finally, "is $9$ ". $=9$

Put it all together to get an expression. $\boxed{3x-2=9}$

Now, let's solve for the unknown number.

Add $2$ on both sides of the equation. $3x=11$

Divide both sides of the equation by $3$ to isolate $x$ . $x=\boxed{\frac{11}{3}}$
