in -2x = - 3.....should I put -2 under both so it would = -3/-2 which would make it 3/2 because of the two negatives or should I put a +2 under both which would = -3/2
thanks

the second side of a triangle is four more than the first side, and the third side is five more than the second. if the product of the first and third sides is added to the product of the second and third sides, the result is 124 more than twice the square of the first side. find the perimeter of the triangle.

i'm involved in a project, now i need a powerfull batteries like lithium ion or nickel metal hydride, maybe powerful. but i only will use li-ion battery or nimh battery as a last resolve. any idea what is more powerful chemical solution/compund that could be more powerful, like able to power a small motor to that support human weight around 70kg and move faster than 30 km per hour?

I did this for 2 weeks and now I am wondering if I need to go back and get another prescription for antibiotics. Will the cold of the refrigerator make them useless. The storing instructions were covered up and I did not see them.

i'm looking for a powerful small motors/engine for a project. the engine is supposed to able to support human weight around 70 kg and move faster than 30 km per hour but i couldn't find it. know where i could find it? if not, then what do i need to build my own powerful engine? also i'm looking for pneumatics for suspension. smaller that the engine if i could.

To specify further, I mean a scan the likes of which could render a realistic image of what's there in various densities. All you would need it a weighted chain or balanced platform connected to circuitry sensitive enough to measure the minute changes that would occur over spots of divergent densities. Something that could discern the outline of, say, a wedding ring to a resolution useful enough to tell what shape the object is.

How far can a human dive before dying? And if it was possible to breath through a liquid in their lungs, would they die at all? Sum the forces and some other garbage. Please explain.

I am hoping I found something genuine here and not just a very old replica. I found this EXTREMELY heavy rock about the size and shape of a regular red brick. This rock has a black film coating on it and has hyroglyphic (not sure on spelling) writing on it. It looks like it is the base of a small statue and the figure is broke off. The place where the part that is broke off has a brown/gold colored rock embedded in it. This piece is also VERY magnetic in certain places. I am going to clean it and get pics sometime tonight. I just wanted to describe this early enough when a lot of people may be on. I am hoping someone has heard of something like this.
