Answer:
C. 5
Step-by-step explanation:
Use the Distance Formula.
Substitute the values of x1 , y1 , x2 , and y2 .
|AB|² =|(1--2)²+(10-6)²|
|AB|² = |9+16|
|AB| = √ 25
|AB| =5
√5 x√5 x√8= √(5x5x8) = √200 = 10 √2
It’s an irrational number
First you can change 3 to 10/10 so that they can have the same denominator. Now, since you do that the number is now 2.
Now, do 10/10-1/10=9/10.
After do 2-4=-2.
So, your final answer is -2 9/10.
