X+4/4=x/x-2 A:{-4,2} B:{-2,4} C:{}

Answer:

The correct answer is B. {-2,4}

Step-by-step explanation:

Let's solve for x, this way:

x + 4/4 = x /x -2

(x + 4) * ((x - 2) = 4 * x

x² - 2x + 4x -8 = 4x

x² - 2x + 4x -8 - 4x = 0

x² - 2x -8 = 0

(x - 4) * (x +2) = 0

x - 4 = 0

x + 2 = 0

x₁ = 4

x₂ = - 2

The correct answer is B. {-2,4}

Write an equivalence chain with fraction that equals 1/2

alexgriva [62]

Hi.

An example of a fraction equivalence chain is this:

$\frac{1}{2}, \frac{2}{4}, \frac{4}{8}, \frac{8}{16}, \frac{16}{32}$

You can keep multiplying $\frac{1}{2}$ by 2 to get a fraction chain.

Hope this helps!
