(2,3) the order is rise over run so, go up two, and to the right 3 which gives you point D
Simplify
4ax+12-3ax=25+3a
ax+12=25+3a
ax-3a=25-12
a(x-3)=13
A cylinder with the same radius and height as a cone will have 3 times the volume of the cone.
Vcone = (1/3)*π*r^2*h
Vcylinder = π*r^2*h
multiply 300 by 7 and then you should be able to finish the equation
32= 4x
That would be the equation and x would then be 8
hope this helps
