Question

What’s the answer to the question shown?

Answer 1

Use the distance formula:

Distance Formula:

d=√(x₂-x₁)²+(y₂-y₁)²

Define the starting point and end point coordinate pairs:

Point A: (2, 3)

Point B: (8, 7)

Input the corresponding values into the formula:

d=√((8)-(2))²+((7)-(3))²

Simplify:

d=√(6)²+(4)²

d=√36+16

d=√52

d=7.211

Rounded to the nearest tenth, the answer is: 7.21
