Step-by-step explanation:
Answer: 3.16 units (Option C)
Step-by-step explanation:
The key to this problem is to use the distance formula, which is:
Distance = 
The first point, T = (x₁,y₁), and the second point, U = (x₂,y₂).
Plugging the two points into the equation, we get:
Distance = 
The values within the parenthesis are subtracted:
Distance = 
The values are then squared:
Distance = 
Finally, they are added together:
Distance = 
can be approximated as 3.16, so the distance between the two points is 3.16 units.

Answer: 21 & 18
Step-by-step explanation:
Sum of two numbers is 39
Difference is 3
Let the numbers be x & y
X+y=39........equation 1
X-y=3...........equation 2
X=3+y............equation 3
Substitute equation 3 into equation 1
(3+y)+y=39
3+y+y=39
3+2y=39
2y=39-3
2y=36
Y=36/2
Y=18
Substitute for y in equation 2
X-y=3
X-18=3
X=3+18
X=21
The two numbers are 21 & 18
