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:

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

105 - 84 = 21

105 - 63 = 42

So the shaded area is either is 21 or 42
