Answer: -6
Step by step:
2x + 3(8) = 12
2x + 24 = 12
2x = -12
x = -6
Assuming width=diameter
diameter/2=radius
area=hpir^2
w=d=2
d/2=2/2=1=r
h=6
area=6pi1^2
area=6pi1
area=6pi
aprox pi=3.141592
area=18.85 cm³
The solution to the equation is x = 0, 2

hope that helps :)
2(4x + 3y). You just factor out the two
