Answer: (2,30), (5,66)
Step-by-step explanation: I truly don’t know if this is correct, but at the beginning, the crystal was already 6 mm. She then realized it increased 12 mm every hour, so if one hour passed, it would be 12+6= 18. Okay, so now that we know that, we multiple the hours by 12 and then add the 6.
12x2= 24
24+ 6= 30,
12x5= 60
60+6= 66
Infinite intervals are closed if they contain a finite endpoint, and open otherwise. The entire real line is an infinite interval that is both open and closed
They are actually equivalent because 3 is a factor of 30 because 3x10
And 10 is a factor of 100 so 10x10
