What is the simplified form of 2/x^2-x - 1/x?

Pachacha [2.7K]

Answer: $\bold{(C)\ \dfrac{3 - x}{x(x-1)}}$

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

$\dfrac{2}{x^2-x}-\dfrac{1}{x}$

$=\dfrac{2}{x(x-1)}+\dfrac{-1}{x}$

$=\dfrac{2}{x(x-1)}+\dfrac{-1}{x}\bigg(\dfrac{x-1}{x-1}\bigg)$

$=\dfrac{2}{x(x-1)}+\dfrac{-x+1}{x(x-1)}$

$=\dfrac{2-x+1}{x(x-1)}$

$=\dfrac{3-x}{x(x-1)}$

The sphere area of a sphere is 200.96 square centimeters. What is the approximate volume of the sphere? Use 3.14 for pi. Round y

julsineya [31]

We are given

area of sphere is 200.96cm^2

it means that we are given surface area

so, we can use surface area formula

$S=4\pi r^2$

where S is surface area

r is radius

so, firstly we need to find radius or r

$200.96=4\pi r^2$

we can solve for r

$r=3.9989cm$

now, we can find volume

$V=\frac{4}{3} \pi r^3$

we can plug r

$V=\frac{4}{3} \pi (3.9989)^3$

now, we can find volume

$V=267.86cm^3$ .............Answer

Yasmin bought several items at the discount store. She paid 8.75 percent

Y_Kistochka [10]

The total amount of her purchase before tax was added is; $52.46

<h3>How to calculate discounted amount?</h3>

We are told that the percentage sales tax she paid on her purchase was 8.75% which translated to an amount of $4.59.

Now, let the amount of her purchase be x. Thus;

8.75% * x = $4.59

x = 4.59 * 100/8.75

x ≈ $52.46
