20 POINTS !!! <br><br> Find the distance between the points (3,-4) and (5, 4)
jeka57 [31]

Answer:

d=2\sqrt{17}\approx8.2462

Step-by-step explanation:

To find the distance between two points, use the distance formula.

The distance formula is:

d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2

Let (3,-4) be x₁ and y₁ and let (5,4) be x₂ and y₂. Therefore:

d=\sqrt{(5-3)^2+(4--4)^2

Simplify:

d=\sqrt{(2)^2+(8)^2

Square:

d=\sqrt{4+64}

Add:

d=\sqrt{68}

Simplify:

d=\sqrt{4\cdot17}=\sqrt4\cdot\sqrt{17}

Simplify:

d=2\sqrt{17}\approx8.2462
