Hi,

Would the answer to the above question (7y - 1) (7y + 1) be:

49y + 7y - 7y - 1 which equals 49y - 1

Please can someone confirm this or correct this.

Many Thanks

Based on this article: http://en.wikipedia.org/wiki/Structural_steel the critical temperature of structural steel is 540 degrees celcius. Based on this article: http://en.wikipedia.org/wiki/Jet_fuel the open air burning temperature of jet fuel is between 260 and 315 degrees celcius. If these numbers are correct, how long would the jet fuel have to burn in order to bring the steel to its critical temperature?

We have high power telescopes on Earth that see with great detail , and satalites that photo in great detail streets on Earth, and I've heard even licence plates on cars.
Point these salalites to the moon and take some pictures.

Walking home just before a thunder and lightning storm one night, i saw 2 strange white spheres the size of a coconut float and seem to be suspended in the air for about 10 seconds before they hit a nearby powerline,when they broke up into 8 smaller golf ball size spheres before disappearing.
Has anyone else seen this strange phenomenon?

I was recently told that for example, when a doctor prescribes medications to a Red Head that the Dr. takes that into consideration. Because Red Heads don't have the same effect as others do to alot of things? ...something having to do with the genetics? Is any of this true?

but plugging that fraction into the point slope formula confuses me.
can anyone explain how to do this?
