Question 167459: Each of the three dimensions of a cube with sides of length s centimeters is decreased by a wholw number of centimeters. The new volume in cubic centimeters is given by
V(s)=s^3 -13s^2+54s-72
A) Find V(10)
B.) If thenew width is s-6 centimeters, then what are the new length and height?
C.) Find the volume when s = 10 by multiplying the lenght,width and height
Answer for C- please inform if incorrect
V(10) =10^3-13(10)^2+54(10)-72
10v=1000-13(10)^2+54(10)-72
1000-1300
-300+540-72
V=168

Question 167832: This word problem involves quadratic equations which I am having a very difficult understanding. The width of a rectangle is 4 ft less than the length. The area is 12ft^2. Find the length and width. I start out translating the equation like this:
A=LW
L=length
4-L=width
12ft^2=L(4-L) then I get lost from that point.

Question 169292: Please help with these two word problems. I just found out from the team leader that she did not post all of our assignments and these two are due tonight from me. I would greatly appreciate your help.
#94. Golden painting. An artist wants her painting to be in the
shape of a golden rectangle. If the length of the painting is
36 inches, then what should be the width? See the previous
exercise ***This is the previous exercise:Golden Rectangle. One principle used by the ancient Greeks to get shapes that are pleasing to the eye in art
and architecture was the Golden Rectangle. If a square
is removed from one end of a Golden Rectangle, as shown
in the figure, the sides of the remaining rectangle are
proportional to the original rectangle. So the length
and width of the original rectangle satisfy L/W=W/L-W.I hope this is understandable.
#84. Gone fishing. Debbie traveled by boat 5 miles upstream to
fish in her favorite spot. Because of the 4-mph current, it
took her 20 minutes longer to get there than to return. How
fast will her boat go in still water?

Question 171431This question is from textbook Algebra 2
: 93. You are taking a pottery class. As an assignment, you are given a lump of clay whose volume is 200 cubic centimeters and asked to make a cylindrical pencil holder. The pencil holder should be 9 cm high and have an inner radius of 3 cm. What thickness "x" should your pencil holder have if you want to use all the clay? (hint: the volume of clay equals the difference of the volumes of two cylinders.)
The answer in the back of the book is "about" 1 cm but i dont know why. Should i use completing the square? ive tried all the cylinder equations and nothing gives me 1.This question is from textbook Algebra 2

Question 171333: A wall of a tent is shaped like a triangle and has an area of 48 square feet. The base of the wall is 2 feet shorter than 3 times the height. Find the length of the base and the height of the wall.
My Work:
A= 1/2bh ------ b=3x-2 --------- h=x
A= 1/2 bh --------- 48= 1/2(3x-2)(x)------- 48=1/2(3x^2-2x)---------- 96=3x^2-2x---- 0= 3x^2-2x-96--------- 0=(3x-?)(x+?)
*** the carrot 2 means "three x squared"
