Answer:

$x=1$

Step-by-step explanation:

$~~~~~x = \dfrac{1}{2 - \dfrac 1{2-\dfrac{1}{2-x}}}\\\\\\\implies x = \dfrac{1}{2 - \dfrac 1{\dfrac{4-2x-1}{2-x}}}\\\\\\\implies x= \dfrac{1}{2 - \dfrac{2-x}{3-2x}}\\\\\\\implies x = \dfrac{1}{\dfrac{6-4x-2+x}{3-2x}}\\\\\\\implies x = \dfrac{3-2x}{4-3x}\\\\\\\implies 4x -3x^2 = 3-2x\\\\\\\implies 3x^2 -4x +3-2x = 0\\\\\\\implies 3x^2 -6x +3 = 0\\\\\\\implies 3(x^2 -2x +1) =0\\\\\\\implies x^2 -2x +1 = 0\\\\\\\implies (x-1)^2 = 0\\\\\\\implies x -1 = 0\\\\\\\implies x = 1$

C

the angle will always stay the same, it won't change

but if the dialation is 1/2, then that means that the sides will decrease in size compared to the original length,

Enter the simplified form of the complex fraction in the box.

Ket [755]

The problem is:

$\frac{\frac{3}{x}+\frac{1}{4}}{1+\frac{3}{x}}$

We now do L.C.M. of numerator and add, also do L.C.M. of denominator and add together:

$\frac{\frac{12+x}{4x}}{\frac{x+3}{x}}$

Dividing by a fraction is same as multiplying by its reciprocal, so we have:

$\frac{12+x}{4x} * \frac{x}{x+3} \\$

x cancels out, so can multiply and write:

$\frac{12+x}{4} * \frac{1}{x+3} \\=\frac{12+x}{4x+12}$

This is the simplified form.

ANSWER: $\frac{12+x}{4x+12}$
