Well this thread died a death so let's revive it with a maths question!

No units but you can put your own in if you want. Apologies for the possible patronising inclusion of how to find area, but after some questions I've seen asked on here I thought it might be necessary.

Winner will receive a signed* picture of Denzel Washington.
If you want a clue the prize will be reduced to a signed* picture of Cher.

* by me.

Also in before any of the usual jokes, i.e. circling area and labelling "there it is" or stating "xy = area".

Yep.
3.125.

I did forget to post more pages, didn't I

I don't want the Cher poster though - if you've had it, I know it will have holes worn in certain areas...

Ding ding ding ding ding! Your prize will be with you within 10 business days.

area = 3.125

Bonus points for proving it! That means you can't just sub in numbers until it works, you need to find it the proper way!

I think this is GCSE maths? It has the level of pointless to it.

a=xy
2x+y=5
and
y=2x

Therefore
4x=5

Therefore
x=5/4=1.25
and
y=2*1.25=2.5

Therefore
a=1.25*2.5=3.125

Nicely done!

duckface gets the signed picture though as he was first to 3.125.

More?

Round 2:

0 = 2x(19-3x)

Find x (both solutions)!

This is still GCSE

I think perhaps higher level, I don't remember. And I only got a C at GCSE

but it looks like you remembered it

I think I lost something important at collage, and it wasnt my virginity

I lost a really good ruler. That was a low point for definite.

Nearly lost my thumb on a band saw as well as it goes
