Answer:
10.770
Step-by-step explanation:
You want the distance between points (-12,20) and (-22,16) using the distance formula.
The distance formula gives you the distance (d) between points (x1, y1) and (x2, y2).
d = √((x2 -x1)² +(y2 -y1)²)
For the given points, the distance is ...
d = √((-22-(-12))² +(16 -20)²) = √((-10)² +(-4)²) = √(100+16)
d = √116 = 2√29 ≈ 10.770330
The distance between the given points is about 10.77 units.
