Solve for x<br> (1/x) - (2x/(1+x^2)) = 0

charle [14.2K]

(1/x) - (2x/(1+x^2)) = 0

Multiply by x(x^2+1)

1(x^2+1)+(−2x)(x)=0x(x2+1)

−x^2+1=0(Simplify both sides of the equation)

−x^2+1−1=0−1(Subtract 1 from both sides)

−x^2=−1

−x^2−1=−1−1(Divide both sides by -1)

x^2=1

x=√±1(Take square root)

x=1 or x=−1

Simon can see two lights, light A and light B.

Vaselesa [24]

Answer:

2 Times

Step-by-step explanation:

Light A flashes every 15 seconds.

Light B flashes every 18 seconds.

First, we determine the next time both lights will flash together.

This is done by finding the Least Common Multiple of the two numbers.

15=3X5

18= $2X3^2$

LCM of 15 and 18= $2X3^2X5=90$

This means that both lights will flash together after 90 seconds.

Now, 4 Minutes =4 X 60 =240

240=90+90+60

Therefore, the number of times more both light will flash together in the next 4 Minutes

= 2 Times

Find the area of the trapezoid with the numbers 4, 3, 3 ,1

quester [9]

Answer:

The answer depends on the shape of the trapezoid...

Step-by-step explanation:

A trapezoid is a 4-sided flat shape with straight sides that has a pair of opposite sides parallel. (trapezium)

Area = (a+b/2) * h

IF the sides are a = 3 ,b = 3 and height = 4

THEREFORE:

(3+3/2) * 4

6/2 * 4

3 * 4

Hope it helped.... Please mark as brainliest..thanks!!!
