HI everyone.




:amaze:

hallo.

What's going on? Not too many people in here tonight I see...




:amaze:

Not a whole lot, I suppose.

How's the idea for 20 coming?

alright guys little math quiz here

if a triangle has a perimeter of 44cm. what is the lenght of each side. and if two sides are 8cm shorther than the long side

show work

I think that I'll have it by the time I go to bed tonight.

Don't strain yourself! ;)

see my above post need this for a math test

crap, i don't remember how to do that stuff...i'm assuming you need help with homework?
i just tried it for the last 10 minutes and can't remember how to do it.
i do know that the sides are: 20, 12, 12.
i just can't remember the proper formula for this kind of problem.

alright yea its hw but a test the teacher lets us take em home
so is there a formula tho

mehh... you and your simple Geometry work. Anyways the answer is H:20 L:12 L:12 and the work would be 3H-16=44 then 3H=60 then H=20 and you can figure out the rest. BAM!! :D

Edit:****.. i umm... added wrong... er something FIXED!

is could H be x?

im confused man

can you make it clearer

erm... i believe the formula would be like... Hypotenus... or something=Leg+Leg and i forgot how to get the Legs...

I know what I want for Christmas, one of those digital recording thingies.

And I'm going to buy some pedals for my electric guitar.

I don't know the 'correct' way your teacher wants it done, but this is how I'd do it.

44 = (x-8) + (x-8) + x

(combine like terms)

44 = 3x - 16

(add 16 to both sides)

60 = 3x

(divide both sides by 3)

20 = x

X is longest side, you can figure the rest out from there.




:amaze:

adn i need to write let satements like
let x = side 1
or like let x-12 = long side its wierd

Ok, now I need math help. I need to factor (and show work):

2(log r)^2 + log r = 1





:amaze:

... that looks like Calc... SPOOKY SCARY!!!

there is only a hypotenuse in right triangles.

[QUOTE=Zap101]... that looks like Calc... SPOOKY SCARY!!![/QUOTE]


Pre-calc ... but we have a quiz on wednesday, and we don't get to use a calculator :(




:amaze:

holy **** luke what is that

stupid grade 9 i hate this

[QUOTE=Spaceman Spiff]there is only a hypotenuse in right triangles.[/QUOTE]

mehh... i never really payed enough attention in Geometry class last year to teach it anyways, so yeah thats right.. your a smart space man :cool:

just a couple more questions n im done

5x/2 -3 = 8 + 2x/3

I suck at posting

Hey All.

Alot.

[QUOTE=ridethelightning]holy **** luke what is that

stupid grade 9 i hate this[/QUOTE]


How about this one ....


sin^2(x) - cos^2(x) = 3sin (x+1)


or


x^2 log (base 3) X = 5x log (base 3)x




:amaze:

Alot!!!

[QUOTE=ridethelightning]holy **** luke what is that

if you hate grade 9 math, you'll REALLY hate grade 10 math.
now i'm doing my grade 11 trig.

lol can you help me with my last post?
and then ill have a couple more after that but i dont no how to do any of this
