Answer:
A. √500
Step-by-step explanation:
Since 500 = 5·100 = 5·10² you can move the 10² out of the √ as 10.
Hence 10√5 = √500
So we're using these rules:
√a·b = √a·√b
and of course
√a² = a (a>0)
It would make sense to be True. Independent lines are,in most cases, constant an could always infinite amount of solutions.
Answer:
28.3 units (3 s.f.)
Step-by-step explanation:

Using the formula above,
distance
![= \sqrt{[6 - ( - 22)]^{2} + (16 - 12) {}^{2} }](https://tex.z-dn.net/?f=%20%3D%20%20%5Csqrt%7B%5B6%20-%20%28%20-%2022%29%5D%5E%7B2%7D%20%20%2B%20%2816%20-%2012%29%20%7B%7D%5E%7B2%7D%20%7D%20)




= 28.3 units (3s.f.)
