Answer:
13.72units
Explanation:
Given parameters:
Coordinates of the two points = (-5.2, 7) and (3,- 4)
Unknown:
Distance between the two points = ?
Solution:
To find the distance between two points, we use the mathematical expression below;
D = 
From the given coordinates;
x₁ = -5.2 x₂ = 3
y₁ = 7 y₂ = -4
Now; input the parameters and solve;
D = ![\sqrt{[3-(-5.2)]^{2} + (-4 -7)^{2} }](https://tex.z-dn.net/?f=%5Csqrt%7B%5B3-%28-5.2%29%5D%5E%7B2%7D%20%2B%20%28-4%20-7%29%5E%7B2%7D%20%20%7D)
= 
= 13.72units
The distance between the two points is 13.72units
Answer:
