Answer:
![x=3](https://tex.z-dn.net/?f=x%3D3)
Step-by-step explanation:
Move the -4 over to the other side.
![3x=9](https://tex.z-dn.net/?f=3x%3D9)
Divide both sides by 3.
![x=3](https://tex.z-dn.net/?f=x%3D3)
4(pi)m^2 = 144(pi)
4m^2 = 144
m^2 = 36
m = 6cm
diameter = 2m
= 2(6)
= 12cm
<span>The nonpermissible replacement for the variable x in this expression is x = 2
Substituting x = 2 yields:
(2)^2/(2(2)-4)
4/0, which is undefined.
