A is always
From what I have B and C are never because one will always end up negative while the other is positive.

A).  |x| = |-x|
This is always true.
The definition of 'absolute' value is 'size of the number without its sign'.
That's what this expression says.

b).  |x| = -|x|
This is never true, because an absolute value is never negative.
This one would true if x=0 .  So maybe some people might say
it's sometimes true, but that doesn't feel right to me.  I say never.

c).  |-x| = -|x|
This looks to me like exactly the same situation as (b),
and I would say all the same things about it.

X^2=60, what is the value of x?
olganol [36]

Answer:

x=2\sqrt{15\\}

\sqrt{60\\}Step-by-step explanation:

To solve this expression we need to isolate x.

This means since x is currently beng squared, we need to do the inverse to it

This means we need to find the square root.

So we root both sides of the equation.

root x^22=x

root 60 is \sqrt{60

which is \sqrt{4*15}

or 2\sqrt{15\\}

Therefore, x=2\sqrt{15\\}
