Question

Find the distance between the two points rounding to the nearest tenth (if necessary).

(-6, 5) and (3,-7)

Answer 1

Answer: 15

Explanation:

Distance formula: a^2+b^2=c^2 where c is the distance.

a^2=

(-6-3)^2=

(-9)^2=81

b^2=

(5-(-7))^2=

(5+7)^2=

12^2=144

c^2=81+144=225

If c^2=225, then what's c?

c=15
