For any real number b, b + (-b)

The answer is 0.

Step-by-step explanation:

Now, here we have to find the value of the expression:

b + (-b)

So here when we open up the brackets, we will get:

b + (-b)= b -b

So we can see that the term b is subtracted from itself and hence we get:

b -b=0

So the final value of the given expression:

b + (-b)= 0

and this is true for any real number b.

the answer is d
