Imagine a plane is sitting on a massive conveyor belt, as wide and as long as a runway.

The conveyor belt is designed to exactly match the speed of the wheels, moving in the opposite direction.

Can the plane take off?

My daughter is 3, & shehas gifts. She has preminitions, often{1-2 a week that we know of} Sometimes she tells us something mundane and it will turn out true. and other times she will flip out about something bad happening, such as not wanting her daddy to go out in the car"because someone will bang into him & he will hurt his head"...we listen to her because of the ammount of times she is right! She also has memories of"when she was big" and will go into great detail. But the most common thing is that she sees fairys. She told us that they keep her awake at night{even though she is asleep} They are on the ceiling, and they are in her words"my teachers", she is not frightened and thinks it is normal. She said there is different ones{colors}, pink blue green and purple &a silver & gold one that she calls the big one or the wishing fairy.She said the green one is funny .She is alusive on what they say, but they teach her to be good.I know nothing about things,can someone help?Any info?

Would you please tell me wether the statements are true or false, and why?
*(+/-) means "positive or negative".

1. iff x^2 = y^2, then x = (+/-)y ,
as in 4^2 = (-4)^2 , 4 = +(-4) or -(-4)

"Obviously", iff x^2 = 9, then x = (+/-)3.
However, is it correct (or usual) to write (+/-)x = 3?

Given x = 25

(square root)x = (square root)25

Should I write (+/-)(square root)x = 5
or
(square root)x = (+/-)5
or
(+/-)(square root)x = (+/-)5 ?

Should the equations be equivalent to one another, please tell me in the answer.

Thank you.
