Answer: C. p = p

<u>Step-by-step explanation:</u>

A tautology is a statement that is always true.

A. p = q

This is not always true. Counterexample: p = 1 & q = 2

B. p = q

This is the same as A (above)

C. p = p

This is ALWAYS true!

D. q = p

This is the same as A but in reverse order.

Licemer1 [7]

Sometimes it will, and sometimes it won't.

I reason as follows:

(21 + x) + (30 + 2x) = 51 + 3x has an 'x' term

(42 + x) + (30 - x) = 72 has no 'x' term.
