2√20 and 4*5^1/2. Explanation Below:
---
When we simplify 2√20, we get 4√5, and 5^1/2 is √5. Therefore, 4*5^1/2 is 4√5.

Answer:
Distance between two points calculator, formula, work with steps, step by step ... Distance between two points = √(xB−xA)2+(yB−yA)2 ( x B - x A ) 2 + ( y B - y A ) 2 ... theorem is used for measuring the distance between any two points A(xA,yA) ... for grade school students (K-12 education) to learn what is distance between ...
Step-by-step explanation:
We won't have a function if for same value of x in (x,y) we get different values y.
So first step: figure out k so that the first coordinate (x) is the same:
3k-4=4k | solve for k
k = -4
no check the values y for the elements of the relation
x = 3k-4 = -12-4=-16
so at -16 we get (-16,16) and (-16, 32), which mean for k=-4 the relation is not a function.
Let me know if you have any questions.
