Answer:
only -2 is in the domain
Step-by-step explanation:
For negative values under the sqrt, there is no real answer, hence
-2x ≥ 0
only for x=-2 this is the case.
The domain represents all the valid input values for x.
19/60 or .317
C = 95/300
95/300 = 19/60
19/60 = .317
15:1
225:15
÷15 both sides
