Question

Almost done with this lesson! A little more help ASAP pls!!!

Answer 1

• C(-5,4)
• D(5,8)

`\\ \sf\longmapsto CD=√((x_2-x_1)^2+(y_2-y_1)^2)`

`\\ \sf\longmapsto CD=√((5+5)^2+(8-4)^2)`

`\\ \sf\longmapsto CD=√((10)^2+(4)^2)`

`\\ \sf\longmapsto CD=√(100+16)`

`\\ \sf\longmapsto CD=√(116)`

`\\ \sf\longmapsto CD=10.4`

Answer 2

10.8

Explanation:

√(5-(-5))² + (8 -4)²

√10² + 4²

√100+16

√116 = 10.8
