$$\\y=ax^2+bx+c\\\\
$The x value for the vertex is $ -b/2a\\
$Then sub the x value into the equation to get the y value $$$

BEDMAS is the same as BODMAS     (is the same as PEDMAS)

just depends on the country you are in.   look here

If you use the input box, you just type it in :)

Maybe you don't know what it means??

3^4  means  3⁴ = 3*3*3*3= 81

Thanks anon but this is not an equation the asker just wants it simplified :)

2(3p+2)+19p

=6p+4+19p

=25p+4

Note:

If it had been equal to 0 your answer would have been perfect:)

I just realized that i wourld say "varies inversely" but the question says "varies indirectly"  

Are these the same thing ?

$$\\C=\frac{k}{P}\\
When\;P=5\; \;C=60\;find\;k\\
60=\frac{k}{5}\\
k=300\\\\
C=\frac{300}{P}\\
When \;P=20\;people\\
C=\frac{300}{20}\\
C=\$15 \;per\; person$$

I have no idea what you are talking about :/

Great answer Zac :)

Zectico, if you think about the answers that you got you will see that they simpley do not makes sense.

e.g.   The car is worth more after 9 years than it was after 4.

Anon,  you started off good but then I don't know what you did :/

(I think i will give you latter 2  points for your efforts  :))

do you just want to divide by the 2 or by  the whole lot.  (in the first one)  

you need more brackets to make your meaning clear.

doesn't make sense
