Question

The volume of a rectangular box is given by the formula v=LWH. The volume of the box is 120Cu. units. find the width and length. ( L=x+2, width=x, ht=5

Answer 1

Ooh, I personally think that this is a fun one :)

Answer 2

Okay, so your equation is v=lwh

Answer 3

You know that the volume is 120, the length is (x+2), the height is 5
so 120=(x+2)(x)(5)

Answer 4

sorry, my internet disconnected

Answer 5

So start by multiplying.
x*5=5x
120=(x+2)(5x)

Answer 6

You can distribute the 5x through the (x+2)
5x(x+2)
5x^2 +10x

120=5x^2 +10x

Answer 7

Can you see how this is turning into a quadratic?

Answer 8

Like a quadratic, you need it to be equal to zero, so move the 120 over.
0=5x^2 +10x -120

Answer 9

Wait- do you know what I mean by "quadratic?"

Answer 10

Dede- if you leave me hanging, I'm leaving :P

Answer 11

I'm watching how you coming about the process.

Answer 12

you mean ax2 + bx + c = 0
