Solve the equation in the complex number system.

tatiyna

To get rid of $x^{3}$ , you have to take the third root of both sides:
$\sqrt[3]{x^{3}} = \sqrt[3]{1}$
But that won't help you with understanding the problem. It is better to write $x^{3}-1$ as a product of 2 polynomials:
$x^{3}-1 = (x-1)\cdot (x^{2} +x +1)$
From this we know, that $x-1 = 0 => x = 1$ is the solution. Another solutions (complex roots) are the roots of quadratic equation.

Solve 0.05p-0.02(5-2p)=0.05(p-2)-0.12

Montano1993 [528]

$0.05p-0.02(5-2p)=0.05(p-2)-0.12$

$0.05p-0.02(5-2p)=0.05(p-2)-0.12:p$

$
0.05p-0.1+0.04p=0.05p-0.1-0.12
 
$ $|Expand \ the \ equation|$

$0.09p-0.1=0.05p-0.1-0.12
 
$

$0.09p-0.1=0.05p-0.22$

$
0.09p-0.1-0.05p=-0.22
 

$ $|Subtract \ 0.05p \ from \ both \ sides|$

$
0.04p-0.1=-0.22
 
$

$
0.04p=-0.22+0.1
 
$ $|Add \ 0.1 \ to \ both \ sides|$

$
0.04p=-0.12
 
$

$0.04p/0.04=-0.12/0.04
$ $|Divide \ both \ sides \ by \ 0.04|$

$p=-3$

$\star \ Hence \ Solved$

PLEASE HELP ASAP I NEED THIS DONE ASAP!!!

Answer:

The value of x is 12.

Step-by-step explanation:

Given that perimeter is found when all sides are added together. So we can assume that all side lengths add together will give you 134 imches :

$x + 2x + 5 + 6x - 17 + 3x + 2 = 134$
