the question reads

solve the cubic equation

3x^3 - 7x^2 - 7x + 3 = 0


i get x=-3 and x= 11/3?? i am pretty sure this will be wrong so any solutions and how u got there will be much appreciated.

i have another which i will add if i get a responce to this one, i would like to try and get the other myself tho, thanks for any help

one afternoon about 4:15pm it was in october. I was driving home from my moms house and all of a sudden I saw a big bright yellow sparkling shooting star in the blue sky. It was in broad daylight. What does this means? Something just kept my eyes looking at the sky. It was pretty big almost as big as a fire works I couldn't believe my eyes. I made a wish after that is my wish going to come true or it already did come true?

A block of cheese has the shape of a cube of size 3 x 3 x 3.
It is divided into 27 small cubes of size 1 x 1 x 1.
A mouse eats small cubes one by one. After finishing a small cube, it eats an adjacent (that shares a face) small cube.

Can the center small cube be eaten last?

Most things about the body have evolved for an evolutionary advantage, so what is the purpose of moles? Is there any at all? Some study has recently suggested that people with more moles have a higher life expectancy - is this truth or fiction?

A manufacturer determines that the relationship between the profit earned, P, and the number of items produced, x, is linear. If the profit is $200 on 18 items and $2660 on 100 items, write an equation expressing P as a function of x. Find the expected profit if 200 items were produced.

If you could answer and show work that would be tremendous

My teacher told me that the only thing we can believe in geometry was that straight lines are straight. I don't think I've used lines that aren't straight...at least yet. So, can I believe that all lines are 180 angles?

A block is given an initial velocity of 2.00 m/s up a frictionless 22.0° incline. How far up the incline does the block slide before coming (momentarily) to rest?


Im sure this is most likely a very simple problem, however I just dont even know where to start! Thanks in advance!

I know how to do it but I don't have a calculator to take the 5th root of something.

- 5 root of (0.323) + 1 = D
The 0.323 is under the fifth root but the 1 is outside of it as well as the negative in front of the root.

Thanks!
