Answer:
B, 4
Step-by-step explanation:
To do this you can use the Pathagaryos thereom a^2+b^2=c^2
So we have (x-2)^2+x^2=20
We can expand (x-2)^2 and get
x^2-4x+4
so we have x^2 -4x +4 + x^2=20
We can combine like terms and subtract 20 from both sides to get
2x^2-4x-16=0
We can factor this and get (2x+4)(x-4)
which means that x=4 and -2
Obviously the length can't be a negative and so we reject x= -2 and we get x=4
We can double check it and see that
(4-2)^2+4^2=20
and it does
Steps to solve:
6 = 2(y + 2)
~Distribute
6 = (2 * y) + (2 * 2)
~Simplify
6 = 2y + 4
~Subtract 4 to both sides
6 - 4 = 2y + 4 - 4
~Simplify
2 = 2y
~Divide 2 to both sides
2/2 = 2y/2
~SImplify
1 = y

Well this is a very vague question... (But I can still answer it since I'm cool))
1 kilometer is 1000 meters so if ya do the math correctly you will get 10,000 meters
But since this is a vague answer I can't be sure since I don't know the time aspect of the question.
Hope this helps my friend

The answer is D. y=2/3x
If you take the coordinates of each points of the line, (-3, -2) and (3, 2) and use the formula to find the slope, then putting it into formula of a line, you get
