4x^2-3x

Okay for answer I got

1
---------
x-2

but I'm thinking that's wrong. If it is HELP! I know I posted another question similar to this but I don't get anything about this stupid Algebra.

Here's the problem:

Object is rolling on surface with minimal friction comes to rest after 198m. Initial velocity is 3.4 m/s^2. If acceleration is constant, what is the acceleration?

What is the formula that gives us acceleration if we only know distance and initial velocity? I can't even find out which one.

So, if you could tell me what formula would work at least, or even go through the problem step by step, that would help. thanks!

ok here are some problems that I'm completely stuck on..can someone help if you know atleast one that would be great I just need help on these six..Thanks

Here I need to condense each expression to a single term.

2 ln (x+2)- ln x

1/2 x log x + log 3 (x+1)

Here I need a single log expression:

Square root sign and under neath it is 3x -5 / 7

4x square root sign and underneath is 10x - 3x

Here I need to solve the exponential equation :

2 log base 5 3x = 4

log base 3 + log base 3 (x squared -8) = log base 3 8 x

?If galaxies spiraled outward from the center during or after their formation then it seems the outer spirals would be older and have more time to develop intelligent life on the planets that orbit their stars and we should search in that direction in our quest for extraterrestrials . However, I don't know if they formed that way or if they coalesced all at once. Just looking at a picture of a galaxy gives the appearance that they are spiraling outward from the center and so could have developed at an earlier time?

The MIBs were men who dressed in black suits, sometimes with glowing eyes or other monstrous features, claiming to be government agents who attempt to harass or threaten UFO witnesses into silence, like they did with the Roswell incident aqnd probably Area 51 too! They went on to be popular into the '60s. The movies with Will Smith were based on the real MIBs. What do you think of this possible conspiracy?

today in psychology we were talking about the two brain hemispheres and we watch a video on a guy with epilepsy and to control it they seperated his left hemisphere from his right. the treatment worked but how do doctors know that taking a risk with such a delicate and essential part of the body wont result in death or other problems? i mean they have to experiment some how dont they? so what do they experiment on animals such as primates since they are the closest thing to us? or do they experiment on human beings?
