Answer:

Step-by-step explanation:
tan 3x=\frac{\sqrt{3} }{3} =\frac{1}{\sqrt{3} } =tan\frac{\pi }{6} =tan (n\pi +\frac{\pi }{6} )\\3x=n\pi +\frac{\pi }{6} =\frac{(6n+1)\pi }{6} \\x=\frac{(6n+1)\pi }{18} \\
where~x~is~an~integer.

x^2+2x-5+3x^2+4x-1
4x^2+6x-6
Answer: 
Step-by-step explanation:
The range is the set of output values for the domain (the set of inputs).
- When x=-5, y=
. - When x=0,
. - When x=2,

So, the range is 
There are 6 balls to every box (a ratio of 6 to 1). Therefore, when there are 78 balls, there are 13 boxes.
