A. Vladimir
Stella was incorrect. She did not multiply 24 feet by 12inches to see how many inches in feet she has total. There are 288 inches in 12 feet, plus the 6 inches is 294 inches. Stella divided the conversion factor instead of multiplying, giving her 2 inches, then added the extra 6 inches giving her 8 inches.

The expressions are simplified to 2x and $\frac{2}{(x+ 1)(x - 1)}$

<h3>How to simply the expressions</h3>

Given the expression;

$\frac{8x^2 - 4x}{4x - 2}$

Let's factorize the numerator;

$\frac{2x( 4x - 2)}{4x - 2}$

Factor the common terms, we have;

2. $\frac{1}{x-1} - \frac{2}{x} + \frac{1}{x + 1}$

Find the Lowest common multiple

$\frac{x(x+ 1) - 2 (x+ 1)(x - 1) + x(x-1)}{x(x-1)(x+ 1)}$

expand the brackets

$\frac{x^2 + x -2(x^2 -x + x -1) + x^2 -x}{x(x-1)(x+ 1)}$

$\frac{x^2+x - 2x^2 -2 + 2x + 2 + x^2 - x}{x(x+1) (x -1)}$

collect like terms

$\frac{2x}{x(x+ 1) (x-1)}$

Divide common terms

$\frac{2}{(x+ 1)(x - 1)}$

Thus, the expressions are simplified to 2x and $\frac{2}{(x+ 1)(x - 1)}$

What percent of 50 is 18

Veseljchak [2.6K]

Greetings!

To find the percent of a number, you mutliply the percent by the number, then divide by 100. We can use this rule to create an equation:
$50*x/100=18$
Multiply both sides by 100.
$(50x/100)*100=(18)*100$
Simplify.
$50x=1800$
Divide both sides by 50.
$(50x)/50=(1800)/50$
Simplify.
$x=36$

36% of 50 is 18.

Hope this helps.
