Respuesta :

We have ( 5x+16 + 8x + 4 - 4x -2 )/3 = (9x + 18) / 3 = 9( x + 2 ) / 3 = 3( x + 2 ) = 3x + 6;

Answer:

The answer is 3x+6

Step-by-step explanation:

Arithmetic mean of those three values can be found into 2 steps:

  • All values need to be added
  • Total value need to be divided to total number of values

[tex]avg=((5x+16)+(8x+4)+(-4x-2))/3=(9x+18)/3=3x+6[/tex]

The answer is 3x+6
