Question

anonymous · Answer

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

anonymous · Answer

Okay, so your equation is v=lwh

anonymous · Answer

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

anonymous · Answer

sorry, my internet disconnected

anonymous · Answer

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

anonymous · Answer

You can distribute the 5x through the (x+2)
5x(x+2)
5x^2 +10x

120=5x^2 +10x

anonymous · Answer

Can you see how this is turning into a quadratic?

anonymous · Answer

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

anonymous · Answer

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

anonymous · Answer

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

anonymous · Answer

I'm watching how you coming about the process.
