Mel's mistake was in the last step, she multiplied by 2 instead of dividing by 2
Step-by-step explanation:
2x + 1 = 19

F(x)+g(x)=(x+5)+(11x-5)=x+11x+5-5=12x using the commutative property.
The least possible height is the height of the cylinder when the volume is 324π cubic inches. To determine that height, we use the formula for the volume of a cylinder. We do as follows:
Volume = πr^2h
324π = π(6)^2(h)
h = 9 inches
