Question

Can some one help me with just this step:

Rewrite the formula using the variable x for the length. Substitute the value of the volume found in step 2 for V and express the width and height of the object in terms of x plus or minus a constant. For example, if the height measurement is 4 inches longer than the length, then the expression for the height will be (x + 4).

Answer 1

look at my first question for volume, length, width, height

Answer 2

If it was morning instead of night, I'd probably be in a better helping mood.

Answer 3

lol

Answer 4

I just need help in writing the formula..

Answer 5

Ok I'm looking at it now.
First you need to round to integer values. (see line 2)
length = x = 8
width = 1
height = 11
I think you need to leave it as V=(1)(11)x
Then replace the (1) with (x-7) and the (11) with (x+3)
so it will be V=(x-7)(x+3)x.
What do you think?

Answer 6

Horrible question, by the way - hard to know where they are going with it.

Answer 7

yeah..rounding is a good idea..

Answer 8

yeah its a very bad question

Answer 9

The fourth paragraph is odd.
Do they mean 77=(x-7)(x+3)x ?

Answer 10

I think so

Answer 11

then maybe you expand and put it as 0=x^3 etc

Answer 12

oh ok..I got it now..thanks for helping...

Answer 13

Yay!

Answer 14
