Answer:
A
3(2x -5)-2(x-5)=3.(2x)-3.(5)-2.x-2.(-5)
=6x-15-2x+10
=4x-5
Answer:
B. 121 I'm sorry if its not correct
V(cylinder)=πR²H
Radius of the cylinder R=x, height of the cylinder H=y.
We can write for the cylinder
V(cylinder)=πx²y
V(cone) =(1/3)πr²h
Radius of the cone r=2x.
We can write for the cone
V(cone)= (1/3)π(2x)²h=(1/3)π *4*x²h
V(cylinder) =V(cone)
πx²y=(1/3)π *4*x²h
y=(4/3)*h
h=(3/4)*y
