Thanks Chris,

I havn't checked properly but it looks good so it gets a tick.

I didn't know that our picture insertion was working.  

The minus sign is not squared so the answer is

y=-36

This makes it a palindromic word.  Like kayak 

Your fraction line is around the wrong way.

Yes it is 12/4=3

$$\left(m^2-\frac{m^2}{2}\right)^{0.5}=\frac{m}{\sqrt2}$$

I had to write it out like this to get my head around it.

$$\mbox{LHS}
=\left(\frac {2m^2-m^2}{2}\right)^{0.5}\\\\
=\left(\frac {m^2}{2}\right)^{0.5}\\\\
=\frac {m}{\sqrt2}\\\\
=RHS$$

Hi SpawnofAngels

Why didn't you leave it as a mixed numeral, then it would have been exact.  

Yes - more info would be good.

You can add a post on the end here or you can write a new post.

You don't need to find the forumula online.

Area of a triangle is 1/2 * base * perpendicular height

It depends what lengths or angles you are given as to how you go about doing this.

Are you talking about a regular hexagon? What info do you have?

Bing translation

What is the opposite of the root cuandrada called?  Doesn't make much sense - is something misspelt?

Kitty, when you answer these can you put your English translation please?
