Question 1013409: I think this is a linear equation, but anyways, here's the problem:
The length of a room is four times its width. If the perimeter is 250 feet, what are the dimensions of the room? I set up two equations:
1) 4l +w=250
2) l -w =0
I used the method of elimination and ended up with:
5l = 250 and then I divided by 5.
The result was l = 50. I divided that by 4 and got 12.5 inches which I presumed was the measurement of the width. My final answer was:
l=50 in and w=12.5 in (there is no dimension specified, but I used inches)
Am I correct, or was I supposed to plug 50 back in to the original equation?
Thanks for helping, and please show your work!

Question 1014141: I am trying to determine the diameter of a cylinder with the requirement that the diameter at one end is 10% larger than the smaller end. How do I calculate it if the length of the cylinder is equal to larger diameter or if the length of the cylinder varies from half to triple the diameter?
for example R1 = 10 R2 = x h = 10
R1 = 10 R2 = X h = 5
R1 = 10 R2 = x h = 18

Question 1014194: Four steps to derive the quadratic formula are shown below.
I x^2+(-b)/a x=(-c)/a
II (x+b/2a)^2=(b^2-4ac)/(4a^2 )
III x=±√((b^2-4ac)/(4a^2 ))-b/2a
IV x^2+bx/a+(b/2a)^2=(-c)/a+(b/2a)^2
what is the correct order?!
