No dont do it this website is s**t they going to track you down and eat your soul

I already answered your question why cant i see my answer?

Im not saying its going to get rid of the spam, its going to get rid of people that ask question that arent related to math but arent spammers.

And yes, they could enter reddit/tumblr/facebook/twitter/4chan etc etc but for some reason they dont. Only god knows why.

It doesnt work. the only way i can see its not related to the topic is if an admin checks it and marks it. By that time they call spam more, and checking if a post is related or not can take time. you know that better than me. They wont spam if every spam post will result in deleting the poster's user.

and adding another forum is no big deal.

CONS:

none (The way i see it)

PROS:

saves time.

i think one of the worst thing a site can be is a human- dependent site.

And this is not the only way to do this, obviously, but i think its a way you can (and should) use.

yeah, but what im saying is we can have a forum for non math subjects, so people who dont spam on purpose can post there.

And the only way to stop the spam is to delete the spammers.

i dont think math jokes or daily quotes are spam, and im not sure about people posting "good morning" every d**n morning or congratulating every new user, but we there are posts that are definitely spam.

this is not a forum for random things, its a math forum. If you want to talk about subjects that arent related to math you can simply enter the "no math forum" or however it should be called and post whatever you want.

and although i usually post as a guest, i think not allowing to post as a guest is an option.

Yes it is.

This is a special type of question:

f(x)

what you have to in those questions is subtract f(x) from both sides and see when 0

you probably dont know what im talking about by now, so ill give you an example (The example you wrote here):

-8(11*x+6)+6(8+5x)=g(x)

2*x+x=3*x=f(x)

g(x)-f(x)=-8(11*x+6)+6(8+5x)-3*x=-88*x-48+48+30x-3*x=27*x-88*x=-61*x>0 add 61*x to both sides and get....

0>61*x divide both sides by 61

0>x

and thats the answer

heres another way to think about it:

if x multiplied by a negative number is bigger than 0 then it means x is a negative number.

why? because if 0 is multiplied by a negative number we get 0 (and 0 is not bigger than 0). if we multiply a positive number by a negative number we get a negative number (and no negative number is bigger than 0)

if we multiply a negative number by a negative number we get a positive number. positive numbers are bigger than 0 and thats what we need.

You cant find x and y if you know only one sides length and 1 angle. you cant solve it. you can express y using x tho.

You dont find it with the law of cosine....

you use the law of cosine to find the length of the triangle's edge. if you want to find the triangle's area you need to use the law:

sin(A)*AB*AC/2=area.

if 7x-12=3x then we can subtract 3x and add 12

4x=12 we can divide by 4

x=3

and thats the answer
