are you finding the volume of a sphere?

because you add the opposite

so it would be 14.2+ 4.9

exponents are when you take something to a certain power 2² would be 4

-27

0.784615385

 12.25 + 17.85 + 15.45 = 45.55 

84.50 - 45.55= 38.95

mean mode and range?

mean is when you add all the numbers in a group then divide by the number of numbers in the group

mode is when you put the numbers in least to greatest then find the middle number

range is the least number to the greatest number ex.  1, 53, 17, 4 the range would be 1-53

y = (2/5)*x // - (2/5)*x y-((2/5)*x) = 0 (-2/5)*x+y = 0 y-2/5*x = 0 // - y -2/5*x = -y // : -2/5 x = -y/(-2/5) x = 5/2*y x = 5/2*y

List the prime factors of each number. Multiply those factors both numbers have in common. If there are no common prime factors, the GCF is 1.

prime is something that is evenly divisble like 4 whereas compsite is something that is not like 17. 1 and 0 are neither
