(x+1)(2x-4)(1/x+1)=(x+1)(2x-4)(1-5/2x-4)

1 answer:

4 0

So you have two parts to eliminate, (x+1) is being multiplied by its reciprocal so you can eliminate that along with the (2x-4).
this brings you to to have 1=(-4/(2x-4)) meaning that if tou multiply both sides by 2x-4 you end up with 2x-4=-4 and can add 4 to both sides, getting 2x=0 or x=0 for your answer. :DDDD

A circle has a radius of 6 in.

-BARSIC- [3]

This is the concept of perimeter of circles, the arc length of the circle will be given by:
(theta)/360*pi*diameter
diameter=2*radius
but;
radius=6 in
diameter=2*6=12 inches
theta=45°
Hence, the arc length will be:
45/360*π*12
=(3π)/2
