Question

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

Answer 1

Answer:

x= 17,1

Step-by-step explanation:

we d= 10

two points (x,4)and (9,10)

by applying distance formula

we have x= 17,1

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
