Answer:

Option A.

Step-by-step explanation:

The given expression is

-25

According to the reflexive property of equality, all values are equal to itself.

a = a

where, a be any real number.

Using the reflexive property we can say that

-25=-25

It means -25 is equal or equivalent to -25.

Therefore, the correct option is A.

Note: If the given expression is \sqrt{-25}, then

\sqrt{-25}=\sqrt{25}\sqrt{-1}        [\because \sqrt{ab}=\sqrt{a}\sqrt {b}]

\sqrt{-25}=5i             [\because \sqrt{-1}=i]

Then the correct option is B.

Blababa [14]

Answer:

Either B or D.

Step-by-step explanation:

I consider both options valid. It all depends on how the employer is keeping track of time, ie if the pay "ticks" every 60 minutes, or an employee is allowed to clock in half hours.
