Simplify completely 8x^3 ÷ 6x^2 - 4x / -2x

artcher [175]

Answer:

Simplified form is $-(\frac{8x^{3}}{3x-2})$ .

Step-by-step explanation:

The given expression is $8x^{3}\div \frac{6x^{2}-4x}{-2x}$

We can rewrite the given expression as $= 8x^{3}\times (-\frac{2x}{{6x^{2}-4x}})$

Further simplification of the expression gives $=\frac{-16x^{4}}{6x^{2}-4x}$

$=\frac{-16x^{4}}{2x(3x-2)}$

$=-(\frac{8x^{3}}{3x-2})$

So the simplified of the given expression is $=[tex]-(\frac{8x^{3}}{3x-2})$

Please help!! The slope of the line passing through the points (-3, 4) and (4, -1) is ___.

oksano4ka [1.4K]

I hope this helps you

slope=m

(-3,4) x'=-3 y'=4

(4,-1) x"=4 y"=-1

slope formula :

m. (x'-x")=y'-y"

m. (-3-4)=4-(-1)

m.-7=4+1

m=-5/7

What is the volume of a cylinder with the base radius of 10 units and a height of nine units?

Otrada [13]

Answer:

$V = 2827.43\ units^3$ or $V = 900\pi\ units^3$

Step-by-step explanation:

The volume of a cylinder is calculated by the following formula

$V = \pi r^2 *h$

Where r is the radius of the cylinder and h is the height

In this case we know that the radius r of the base is:

$r=10\ units$

and

$h=9\ units$

So the Volume is:

$V = \pi (10)^2 *9$

$V = 900\pi\ units^3$

$V = 2827.43\ units^3$
