Given:
• Points are : ( x , -1 ) and ( 3 , 2)
• Distance between points is 5 unit.
To find :
• The value of x .
Solution :
• As we know that :
Here ,
• x1 = x and y1 = -1
• x2 = 3 and y2 = 2
• d = 5 .
Hence ,the value of x is 7

Answer:
Step-by-step explanation:
Let the points (x,-1)be (x1,y1) and (3,2) be (x2.y2) have a distance of 5 units.
using distance formulae [(x1-x2)^2 + (y1-y2)^2]^1/2 we get
[(x-3)^2 + (-1 -2)^2]^1/2=5
(x-3)^2 + (-3)^2 =5^2
(x-3)^2 + 9 = 25
(x-3)^2= 16
x-3 = -4,+4
x= -1, +7
I hope this helps.
