Question

Find the distance between these points W(-6,-8) , X(6,8) ○20○10○8

Answer 1

the distance between W(-6,-8) and X(6,8) is given as follows,

`WX=\sqrt[]{(8-(-8))^2+(6-(-6))^2}`
`WX=\sqrt[]{(8+8)^2+(6+6)^2}`
`\begin{gathered} WX=\sqrt[]{16^2+12^2} \\ WX=\sqrt[]{256+144} \\ WX=\sqrt[]{400}=20 \end{gathered}`

now, the length is WX = 20, so the correct answer is option A.
