I know this is an easy problem but I just can't figure it out.

If x^2 + y^2 = 73 and xy= 24, what is the value of (x+y)^2?

A 73

B 97

C 100

D 121

E 144

I tried working it but couldn't get it to work. :( Can somebody help? Thank you!!

"The average of the test scores of a class of p students is 70, and the average of the test scores of a class of n students is 92. When the scores of both classes are combined, the average score is 86. What is the value of p/n ?"

I tried but all I keep getting is the identity theorem...

Apparently a =

3, 4, 5, 6, or 7.

I know this is a dumb question but somebody please tell me how you can factor it and get a real number value for a without any other info in the problem...

Does anybody know of a specific formula in civil engineering that uses a math formula, preferably something that uses Precalculus topics such as natural log or limits, etc? I was thinking along the lines of some equation calculating material resistance or like the curing time for cement or something. Please help, thanks in advance!

I have a presentation for a school project coming up and I was wondering how to improve my sales pitch and general public speaking abilities. Usually during speeches, I unknowingly talk very fast although I'm not "really" that nervous. Also, how should I connect to the audience more? I always feel like I'm on auto-pilot and ramble on and not really talking to the audience. Thanks for any tips!!

I want to participate in a 7 week foreign language exchange program over the summer but it costs around 5000 dollars. Besides earning scholarships (through essays/applications, etc), are there other good and effective ways to do this? Is there such a thing as writing to a local company and asking them to sponsor me by donating money? Thanks!

What exactly is it for? Thanks.

Has anybody taken all three of these classes/exams? Which class was the easiest and hardest? I have taken AP World this year and it was relatively easy and am planning to take US and European both next year.

I'm looking for a French movie where a girl takes a walk every morning at the same time (7:00) because she really likes the philosopher Immanuel Kant and that's what he did every morning. Does this sound familiar to anybody? I don't know the central plot, but does anyone knows what film this is?

Thanks!

Does anybody know specifically? Or, I heard that he could speak 15, but does anybody know which? Thanks!

Si j’avais 1.000.000 €, je voyagerais à au moins six pays et leurs grandes villes. Is this grammatically correct? Or, should à be replaced by something else? Thanks!

Does anybody think this is too hard or too much history for one year? Along with these two, I would also take Honors English, Honors French IV, Honors Chemistry, 1/2 year of gym/drawing I, Honors PreCalculus, which is my sophomore year. I took AP World History as a freshman, along with Honors English, Honors French III, Honors Biology, 1/2 year of gym/health, and Honors Algebra II with very good grades in all.

I do like history, but does it sound like too much?

Thanks!

Does anyone think this will be too difficult? Two science classes of Honors Chem and Physics? I'm also planning on taking Honors PreCalculus, Honors English, Honors French 4, AP U.S. History, 1/2 of Gym and Drawing 1. This will be my sophomore year. For my freshman year, I took Honors Algebra II, Honors English, Honors French 3, AP World History, 1/2 gym and health, Advanced Orchestra and I still had very good grades. I am okay in the sciences, but does this seem like too much science in one year?

On average, how many SAT II Subject Tests should an Ivy League applicant take? Is it possible to take too many and have a negative effect on your application? Should you only take these tests after taking an AP class over the same subject or will completing a regular/honors class be enough to take a subject test? If not, would it be a bad idea to take a subject test over all the courses you've taken in school, like Biology, World History, US History, Chemistry, Physics, Math II, Literature, Chinese, French?

Thanks for any info!

For the past two days, my default font in Microsoft Word of Times New Roman, size 12, unbolded has always come up looking bolded. I have not changed any settings, and cannot seem to get it back to the "original" formatting. If I bold the text, all the words become even more bolded. Can anybody help?

Ever since I got broadband through a broadband modem, my PC hasn't been able to go into standby. However, if I go to "View Network Connections" and manually disable the Local Connection, it can be put into standby. Is there a way to fix this and make the computer standby without going through these annoying steps? Thanks!

Does anybody have any advice on getting to know people you kind of know better? They're not exactly good friends but I would kind of want to be better friends with them. How would you start conversation? When? And what would you talk about?

Thanks!

Is there anything in particular anybody uses to start conversation to get to know others better? I have found that for me, I usually don't know what to say around people I have just met so it's harder for me to make new friends, etc. On the other hand, I've seen some people meet totally new people and seem to be good friends within a few minutes. Can anybody offer any advice for me?

I would greatly appreciate any help!

About the SAT II's,

1. How is it different than SAT I?

2. What year in high school do you take it?

3. Do colleges require it?

4. Which subjects do you take? Or do you choose?

5. Do you take a subject after you learn it in high school or can you take a subject even if you didn't learn it in high school?

6. Do colleges have to see all the SAT II tests you take?

If somebody can give me more information about the SAT II, it would be greatly appreciated!
