Question

Find the value(s) of x for which the distance between the points P(X,4) and Q(9,10) is 10units

Answer 1

Answer:

x= 3 because 9,10 distance=1

and 3 to10 distance4,5,6,7,8,9

Answer 2

Answer:

⇒ (PQ)2 = (10 units)2 = 100 units2

⇒ (9 – x)2 +  (10 – 4)2 = 100

⇒ 81 – x2 – 18x + 36 = 100

⇒ x2 – 18x + 17 = 0

⇒ (x – 1) (x – 17) = 0

⇒ x = 1  or  x = 17
