or factor

- anonymous

okay ill make this more specific try to factor x^2-36

- anonymous

To factor x^2-36=(x-6)(x+6) and to simplify the original problem is -x-6/7x but I was only able to do that because of a program online.

- anonymous

do you want to learn how to do it normall or do you just want me to check your answer?

- anonymous

I'm going to be honest with you, this Algegra course I'm on is the last course I have on my online High School Diploma course. This exam I'm on is the last one for the whole course! And I mean I may be a lot better at everything else and not cheat and whatnot but math is just not my thing. I don't know anything about it and I am 100% sure that I do NOT need it for my career choice. If you know how to do this, and you are 100% sure that you give me the correct answer, please, please, please help me! This is the last obstacle I have before receiving me High School Diploma. Please, help?

- anonymous

my*

- anonymous

okay so first of all the answer should be c.

- anonymous

Are you positive?

- anonymous

positive

- anonymous

Thank you so much! On the off-chance that I should fail this exam and need further assistance, would you be willing to help?

- anonymous

no problem

- anonymous

- anonymous

:)

- anonymous

im glad to help,

- anonymous

Okay, I have one more actually if you would be willing to help. See I have all the exams for the course and most of the second attempts that they give you and on this particular exam I have an 85 and a few wrong. My overall grade for the course is 62 right now. So if I get an 100 on this exam that should boost my overall grade to 65 and pass the whole thing. So I'm thinking if you were to help me with one more, that will increase my chances.

- anonymous

no prob whats the problem?

- anonymous

Alright one second, I gotta take a screenshot of the question and all that..one sec..

- anonymous

no problem

- anonymous

Ok, here it is: http://i1255.photobucket.com/albums/hh639/zigzagoon20001/Q6_zps9eb377f2.png Obviously the answer isn't A haha

- anonymous

okay without even doing the problem I knew the answer just from what q cant equal. the denominator can never be 0 so q can never be -2 because then the denominator would be 0. so d is the answer but just to make sure I did the problem anyway and it is d

- anonymous

Alright, thank you so much! I really, really appreciate it. Hopefully the second attempt to this exam is 100% the same as the first which they usually are, and I pass the whole course. Thanks a bunch!

- anonymous

no problem

- anonymous

One more, and that it all, I promise. If I get this next question right, and of course the other ones you helped me I will get an 100

- anonymous

lol I have no problem with helping you :D its okay to ask me what is it?

- anonymous

http://i1255.photobucket.com/albums/hh639/zigzagoon20001/Q13_zpscf4c5d2b.png Here ya go (: Thank you again lol

- anonymous

hmm something seems wrong with that, check th picture is that exactly whtas on your page?

- anonymous

like is it supposed to be -6x-9x or is it supposed to be -6x^2 -9x?

- anonymous

okay im pretty sure there is an error but I get a reminder of -51 but Im not sure if the answer is a or b

- anonymous

Okay, well we'll see I'm going to submit the answer as A and submit the exam in like 5 minutes. Hopefully I pass and get everything right, wish me luck!

- anonymous

luck! tell me how you do!

- anonymous

Well that last one wasn't -51 and it didn't raise my grade high enough but I have two others with just a few questions that were wrong and I can take it again, if you'd be willing to help?

- anonymous

sure

- anonymous

Okay here it is: http://i1255.photobucket.com/albums/hh639/zigzagoon20001/Q20_zps96bfe0b4.png

- anonymous

Obviously B was wrong haha

- anonymous

k one sec

- anonymous

Ok

- anonymous

d
u take one area and subtract other

- anonymous

Ok, I just tried to redo that exam, and it kinda shuffled the questions and replaced some with new ones, if you'd be willing to help me on at least 10? That would be great, but if you don't want to it's alright, but it would really be great though hahaa :)

- anonymous

I can try my best

- anonymous

Thank you so much again..lol..um here's the first: http://i1255.photobucket.com/albums/hh639/zigzagoon20001/Q1_zpseecccc78.png

- anonymous

kay its A next one

- anonymous

http://i1255.photobucket.com/albums/hh639/zigzagoon20001/Q2_zps3c3b1c80.png

- anonymous

A

- anonymous

One second

- anonymous

take your time

- anonymous

Okay, most of these next ones will have to be actually typed out because they are teacher graded so here is this next one: "Order 34 x 10^2, 1.2 x 10^7, 8.11 x 10^-3, and 435 from least to greatest."

- anonymous

easy
8.11 x 10^-3
435
34 x 10^2
1.2 x 10^7

- anonymous

Thanks, please hold for the next one, I may already have the answers for a few of them from the first attempt.

- anonymous

no problem, Im pretty much studying for chem anyway

- anonymous

Cool, and thanks again btw, I would have been absolutely screwed w/o you heh..

- anonymous

no problem

- anonymous

Here it is, actually quicker than I thought haha. I remember this one being one of the ones that I got wrong from the first attempt: http://i1255.photobucket.com/albums/hh639/zigzagoon20001/Q2_zps6fa3a22a.png

- anonymous

okay surface area of a cube is 6a^2 so
6(4x-5)^2
=96x^2-240x+150
that's a

- anonymous

and b is
volume=a^3
=(4x-5)^3
=64x^3-240x^2+300X-125

- anonymous

Alright, I'm gonna go over the next answers and see which ones I don't have the answers to, please hold (:

- anonymous

okay

- anonymous

so howd it go
did you get a mark?

- anonymous

Okay, here's the next, finally lol: Find the next three terms of the sequence. Then write a rule for the sequence.
648, 216, 72, 24

- anonymous

8,8/3 or 2.666,and 0.88889 or 8/9. and the rule is take the number and then divide it by 3 to geth the next term. I know theres a special way to write that but I cant remember so try to word it as best as you can.
also at my time zone its 10;15 at night and I gotta to leave soon so send me as many questions as you need in the next 15 min before I have to leave
and if you don't finish your test before I leave inbox me cause im curious to know how it went! K?

- anonymous

Alright, and thanks again. And I will definitely tell you how it goes, but I will get the final results once the actual "teacher" grades it, but I will tell you when I get it back (:

- anonymous

And that is actually all the questions I have for now though so unless I have to retake the whole course, which may be likely..I will let you know as well. And thanks...like thank you so much...I know I already said it a thousand times, but thanks.....haha thank you (:

- anonymous

I'm glad that I could help, you seem like a really nice person and I like helping people so honestly it was no problem. By the way what grade level was that course. cause that stuff was old for me

- anonymous

and ive been up to calculas and have taken some university math, so if this is a final course I expected it to be super advanced but that was kinda simple
like there was no calculas or trig or integration...

- anonymous

Yeah I'm assuming this would have been on the 12th grade level because it was the last course but I don't really know.
