Answer 1

do you have any clue of what to do first?

Answer 2

Absolutely none, I'm sorry.

Answer 3

no problem, okay try to simplify
do you know what that means?

Answer 4

or factor

Answer 5

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

Answer 6

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.

Answer 7

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

Answer 8

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?

Answer 14

Answer 15

Answer 16

:)

Answer 17

im glad to help,

Answer 18

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.

Answer 19

no prob whats the problem?

Answer 20

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

Answer 21

no problem

Answer 22

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

Answer 23

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

Answer 24

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!

Answer 25

Answer 33

Answer 47

One second

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

Answer 56

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

Answer 57

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

Answer 58

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

Answer 59

okay

Answer 60

so howd it go
did you get a mark?

Answer 61

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

Answer 62

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?

Answer 63

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 (:

Answer 64

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 (:

Answer 65

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

Answer 66

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...

Answer 67

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.
