-6x-4+5x=4<br> What is "x". Please show your work.
4vir4ik [10]

Answer:

first thing to do is combine like terms

now you would have -x-4=4

this is because you added -6x+5x

now you would add 4 to each side

now you would have-x=8

then you would divide the negative because x has to be positive

now you would have x= -8

that is your answer. if you any questions just ask :D

Given z^3 = 3 + square root 3i which letter represents z
Marianna [84]

The expression that represents the value of z is \sqrt[3]{3 + i\sqrt 3 }

<h3>What are complex numbers?</h3>

Complex numbers are numbers that have real and imaginary parts

A complex number (n) is represented as:

n = a + bi

From the above expression, we have:

  • a represents the real part
  • bi represents the imaginary part

Given that:

z^3 = 3 + \sqrt 3 i

Rewrite the above expression as:

z^3 = 3 + i\sqrt 3

Take the cube roots of both sides

z = \sqrt[3]{3 + i\sqrt 3 }

The letters are not given.

Hence, the expression that represents the value of z is \sqrt[3]{3 + i\sqrt 3 }
