We are doing quadratic equations in class and I need help in trying to find the TWO x-axis's.

I remember that to find the x-axis you make y equal to 0. But for example take this equation:

x (squared) + 5x + 4 = 0
x (squared) + 5x = -4
Then what am I supposed to do with the squared, do I square root it?

I also have another question..

In this equation:

x = -b + (square root of) (b(squared) - 4ac)
----------------------------------------------
2 (a)

is that how I find the two x-intercepts! please help! thank you!

Suppose that the monthly cost of a long-distance phone plan (in dollars) is a linear function of the total calling time (in minutes). When graphed, the function gives a line with a slope of 0.13.

The monthly cost for 42 minutes of calls is $16.18 . What is the monthly cost for 47 minutes of calls?

2 ships leave port at exactly the same time.
Ship A travels at 12 kilometres per hour on a bearing of 073 degree.
Ship B sets out at 15 kilometres per hour.

After 3 hours the two ships are 30 km apart.

Calculate, to the nearest degree, the bearing Ship B must have followed when leaving port.

I am really stuck with this one, must be late , or maybe the time change!! ;-) Help really appreciated!!

I heard that you can set water on fire if there is methane and a spark- is it true? How is that possible? I thought water doused fire.
