Answer: x=2
Step-by-step explanation:Algebraically solve this equation. First subtract x from 2x which gets you just x. then subract 3 from 4 which gets you 1. Then subract 1 from 3 which gets you to the equation x=2. You can plug it in and check
2(2)-3-2+4=3 which is 4-3-2+4=3 which is -1+4=3 which is 3=3 which is correct.
Hope this helps :)
The formula of density is mass / volume.
So, the volume is equal to the area of the cube by the total height, so the area of the cube is 3x3= 9, and this result multiplied by the height, 9x3 = 27.
Following the formula of density, we have 216 g / 27 cm^3, the result is 8 g/cm^3.
Hope you undestand my procedure XD
