the number r is irrational. which statement about 8 + r is true

Answer 1

If \( r \) is an irrational number, then \( 8 + r \) is also irrational.

This is because the sum of a rational number (in this case, 8) and an irrational number (in this case, \( r \)) is always irrational.

To summarize, the correct statement is:

8 + r is irrational.
