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

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

1.

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;

2x

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)}

Please Help me with X and Y
Bad White [126]

Answer:

a) x = 69°

b) y = 69°

Step-by-step explanation:

a. Given that AB and CD are parallel lines, therefore:

x = 69° (alternate interior angles are congruent to each other)

b. y + 111° = 180° (consecutive interior angles are supplementary)

y = 180° - 111° (substraction property of equality)

y = 69°

3(2x + 4) = 72 <br><br> What’s x
Tresset [83]

Answer: x = 6

Step-by-step explanation:

(3)(2x) = 6x

(3)(4) = 12

12-12 cancels out

72-12 = 60

6x/6 cancels the 6 out

60/6 = 6

x = 6
