Answer:
√185 = 13.6
Step-by-step explanation:
Distance² = (x' - x)² + (y' - y)²
Distance² = (-7 - 4)² + (5 - -3)² = (-11)² + (8)² = 121 + 64 = 185
Distance = √185
Answer:
False
True
False
False
Step-by-step explanation:
1. We have to get the sum as follows :

= 
= 
= 
= 
So, this is false.
2. We have to get the sum as follows :

= 
= 
= 
= 
So, this is true.
3. We have to get the difference as follows :

= 
= 
= 
= 
So, this is false.
4. We have to get the difference as follows :

= 
= 
= 
= 
So, this is also false. (Answer)
