2x+1
Step-by-step explanation:
(4-2x), (-7-3x),(11x+6)
Add the three expressions
(4-2x)+ (-7-3x)+(11x+6)
Combine like terms
-2x-3x+11x+4-7+6

Answer: 0.22 kilolitre
Step-by-step explanation:
First, let’s find the volume of the tank. We know the volume of a cylinder is represented by the equation V=πr^2h,
Radius = 1 m
Height = 7 cm = .07 m
The tank is 0.22 cubic meters
Now that we found the volume, we will try to find how many liters are in the tank.
1 cubic meter = 1 kilolitre
So, 0.22 cu. m = 0.22 kilolitre
