Final answer:
Both Sammy and Teemu are correct. Teemu is correct in describing the coefficient, and Sammy is correct in stating that the expression is the sum of four terms.
Step-by-step explanation:
In this case, both Sammy and Teemu are correct.
Teemu is correct in describing the coefficient, which is the number multiplied by a variable term. In the expression 1/2bh + 4, the coefficient is 1/2, as it multiplies the term 'bh'.
Sammy is also correct in saying that the entire expression is the sum of 4 terms. The expression can be broken down into four terms: 1/2bh, 4, 0, and 0.
