Answer 1

Answer:

C. R is not equal to -10

Step-by-step explanation:

Restrictions usually deal with preventing the case of dividing by 0. In this case, you'll look at the denominator.

If R = -10 and 10 was added to it, then the denominator would become 0.

Therefore, the expression would be messed up.
