I'd like to take the bus down to the local Barnes and Noble to get a book or two but it sucks being stuck in an air conditioned condo when it's 100 degrees outside. It takes 5 min. to walk to the bus stop and it takes another 3 min. or so to walk from the bus/trolley station to B&N.

Should I be careful and go to B&N or should I just forget it and wait until it gets cooler in the week?

I think the above should explain it all, but can you die of fright? Can you become so distressed that it disrupts the heartbeat and/or brain function, or stops it altogether? You hear about this kind of thing all the time in books, movies, etc., but I've never heard of it happening in real life.

Thanks!

If its true then wouldn't it be a disadvantage to dark-skinned people because they live in sunny areas and hence more prone to heat stroke?

Have a look at this:

X + X = X
2X = X
2X - X = X - X
X = 0

Is this possible? Or is the equals sign not supposed to be there because 2X Actually doesn't equal X?

solve using the qudratic formula:
x*2-3x-10=0

*2=means x squared


please show me how to solve this in a step by step process...it is a practice question on a practice test....if you have any questions...'email message' me from my profile!

Examining my Bic Ultra pen I noticed the cap has a hole in the cap, presumably to let ink flow out in case the pen explodes. Which seems like a bad idea. So perhaps the hole is to prevent pressure which would cause an explosion? Which leads to my question...Why do pens explode?
