Question

Find the legth of DE using the distance formula. D= The length of DE is

Answer 1

10

Explanation:

Answer 2

`\huge\boxed=10`

Explanation:

`d_(DE)=√((x_E-x_D)^2+(y_E-y_D)^2)\\\\D(-4,\ 2)\to x_D=-4,\ y_D=2\\\\E(4,\ -4)\to x_E=4,\ y_E=-4\\\\\text{substitute}\\\\d_(DE)=√((4-(-4))^2+(-4-2)^2)=√(8^2+(-6)^2)=√(64+36)=√(100)=10`
