Answer: \frac{6-x}{x^{2}-2x}

Step-by-step explanation:

Find the least common multiple (LCM) of the denominators. This is:

LCM=x(x-2)

Divide the LCM by each denominator and multiply the result by each numerator, then you obtain:

\frac{2x-3(x-2)}{x(x-2)}

Apply the distributive property, then you obtain:

\frac{2x-3x+6}{x^{2}-2x}

Add like terms, then you obtain:

\frac{6-x}{x^{2}-2x}

<u>Answer:</u>

The correct answer is \frac { 6 - x } { x^2 - 2x }.

<u>Step-by-step explanation:</u>

We are given the following expression and we are to simplify it by finding the difference of these two rational terms:

\frac {2} { x - 2 } - \frac { 3 } { x }

Taking their LCM to get:

\frac { 2x - 3 ( x - 2 )} { x ( x - 2 )}

\frac { 2x - 3x + 6 } { x^2 - 2x }

\frac { -x + 6 } { x^2 - 2x }

\frac { 6 - x } { x^2 - 2x }

vodka [1.7K]

Answer:

A. because it earns interest

Step-by-step explanation:

The interest rate is the gaining that you make for keeping your money in the bank. Suppose you have $100 and the bank offers you a 5% annually interest rate. The rate (5%) means that your money will earn five percent of the value each year, so after the first year you will earn (5%)*($100) = $5 of interest just for keeping your money in your savings account. Therefore, your money will grow overtime because it is earning interest. Remember that interest can be compound (over periods) or simple (like our example).
