Question

Find the distance between A(12, 8) and B(4, 2).A) 14 unitsB) 10 unitsC) 100 unitsD) -10 units

Answer 1

Using the distance formula:

`d=√((y2-y1)^2+(x2-x1)^2)`

Where

(x1, y1)==> (12, 8)

(x2, y2) ==>(4, 2)

Substitute the values into the distance formula above;

`\begin{gathered} d=\text{ }√((2-8)^2+(4-12)^2) \\ \\ \text{ = }√((-6)^2+(-8)^2) \\ \\ =\text{ }√(36+64) \\ \\ =√(100) \\ \\ =10 \end{gathered}`

Therefore the distance is 10 units

ANSWER:

B) 10 units
