12. a+c

Answer 1

A. xy ← This is the product of two terms ("x" and "y") so this is NOT the sum of exactly two terms.

B. m⁴ + 6n ← "m⁴" is one term and "6n" is another term and they are being added so this IS the sum of exactly two terms.

C. 3 + 7s + t ← "3" is one term, "7s" is one term, and "t" is a third term. So this is the sum of three terms so this is NOT the sum of exactly two terms.

D. a + c ← "a" is one term and "c" is another term and they are being added so this IS the sum of exactly two terms.
