Hi,

The distance between points (3,0) and P is five which of the following points could not represent P ?

D = sqrt+%28%28x%5B1%5D-x%5B2%5D%29%5E2%2B%28y%5B1%5D-y%5B2%5D%29%5E2%29%29

A. (3,-5)

D = sqrt+%28%283-3%29%5E2%2B+%280-%28-5%29%29%5E2%29%29 = 5

B.(-2,0)

D = sqrt+%28%283-%28-2%29%29%5E2%2B%280-0%29%5E2%29%29= 5	

C.(8,0)	

D = sqrt+%28%283-%288%29%29%5E2%2B%280-0%29%5E2%29%29 = 5

D.(3,5)

D = sqrt+%28%283-%283%29%29%5E2%2B+%280-5%29%5E2%29%29 = 5

E.none of these

E would need to be the answer
