How to get grades up?

[samsquared]

but isnt it -3(3x(4-5))^2 so its -3(12x-15x)^2 tho?

also you cant simply take the square root of a negative number, then it becomes imaginary and you gotta put some i's in there

oh yeah
my bad ( = w = );;;
but I have no idea if that was (4-5) or (3x4)-5. More parentheses please.

 

[tobi!]

yeah i already said that....

But you would you put the i in? When I was in Algebra 1, we just put no solution. I think Algebra 2 introduces i

 

[Jarrad]

Yeah, no problem.

and idk I think Jarrad might be right on this one. You use the spray bottle on your pet when she/he does the bad thing, not because she/he did a bad thing.

this.

 

[LambdaDelta]

Yup, that's right.

But really, who are we to punish her? We aren't the authoritative figures in her life. I'm sure that her parents are just as disappointed/angered as other people in this thread are, and that she's being punished by them.

I mean, she's been excluded from school, so measures are being taken to send a message to her.

>is being punished by parents
>is posting on the internet

what

yes in algebra 2/trig you do

 

[Tessie]

btw you guys i got X = 0.33i

please mathematicians check if correct

 

[SuperVandal]

Yes, it will. You're arguing that tormenting a bully yields the same outcome of educating and guiding a bully onto the right path...

Since when does stating the truth render someone "high and mighty"?

Enlighten me, please. Whenever did I say "tormenting" would lead us anywhere? I'm merely pointing out that your logic is flawed and produces nothing of a coherent conclusion. What you're suggesting is, as I've stated, putting the blame elsewhere that doesn't actually put her at fault.

And by her posts on this thread, it is somewhat apparent that she didn't learn anything from neither her punishment nor the "education" you're handing out.

And for the record, automatically assuming everything you post is the "truth" is what makes you stand out as arrogant.

>is being punished by parents

what

yeah, computers have kind of become a necessity and much less a privilege

anyway, i dont know this girl, nor do i know how she's being parented/disciplined

 

[Tessie]

heres my work lucky but dont COPY cos im not sure if its right good luck ok babygirl


-3((3x)(4-5))^2 =13
-3(12x-15x)(12x-15x)=13
-3(144x^(2)-180x^(2)-180x^(2)+225x^(2))=13
-3(144x^(2)-360x^(2)+225x^(2))=13
-3(39x^2)=13
-117x^(2)=13
117x^(2)=-13
Sqrt(117x^(2))=sqrt(-13)
10.8x = sqrt(-13)

10.8x = i(sqrt)13
X = 0.33i

 

[tobi!]

btw you guys i got X = 0.33i

please mathematicians check if correct

what was the equation

 

[Tessie]

OK WOLFRAM SAID IM COMPLETELY WRONG NVM THAT LOLLLL


now im embarrassed

- - - Post Merge - - -

wolfram siad its -27x^2 = 13 now how the heck did they get that shenanigans

 

[broadwaythecat]

omg mr cox used to be my teacher

eh.. best thing to do is study a little every day

 

[samsquared]

Okay, take two.

-3(3x(4-5))^2=13
-3(3x(-1))^2=13
-3(-3x)^2=13
-3(-3x)(-3x)=13
-3(9x^2)=13
-27x^2=13
x^2=-0.481481
x= sqrt(0.481481)i

or something

I'm still terrible at math.

EDIT://
AAH! Tessie says Wolfram gave this answer, too! Hooray, I think I got it!

 

[Tessie]

Okay, take two.

-3(3x(4-5))^2=13
-3(3x(-1))^2=13
-3(-3x)^2=13
-3(-3x)(-3x)=13
-3(9x^2)=13
-27x^2=13
x^2=-0.481481
x= sqrt(0.481481)i

or something

ooooh....DUH you subtract 4-5 first >.<

i distributed 3x with 4 and -5 and multipled them first. i forgot order of operations, PEMDAS

youre correct! <3

Oh gosh your so smart! sorry I was watching a video then I was going to part 2

 

[Tessie]

^ NO IM NOT RIGHT DONT LISTEN TO ME


lancetheturtle solved it

 

[LambdaDelta]

yeah, computers have kind of become a necessity and much less a privilege

they're necessary to an adult, not a child

and if they do need to use it for anything productive, then they should be supervised while its being used so that they cannot be posting on social media sites such as this

goddamn

 

[SteveyTaco]

I am legitimately done with this thread now like WTF.

Spoiler

Goodnight everybody!

 

[Mercedes]

I am gonna study and be as smart as you all and LD I am aloud to have my cell phones social media, and Internet.
