1/6 of an hour is 10 minutes because there are 60 minutes in an hour so 60/6=10 so it's 25m^2/10minutes now just multiply 25 by 12 ( 12 lots of 10 minutes in 2 hours) 25*12=300 answer is 300m^2
I guess that You made a mistake and You wanted to solve equations . Then the answer is D because There is no number that gives a negative number after the square root
So you will have to find the difference between each number so 6--2=8 and 8--2=10. So then I'm guessing you have to round 8 to 10. Sorry if this isn't all correct.
A fraction. I.E. : 6 has 36 parts (6 parts per one) If you took 2 out of the six parts away you would get 32/6 or 5 2/6 (2/6 could be simplified to 1/3)
