What is the simplified form of 3p - 7 + 2p?

• A. 5p - 7
• B. 1p - 7
• C. 3p + 7
• D. 2p - 7

Answer: (A)

To simplify the expression 3p - 7 + 2p, it is essential to recognize and combine like terms effectively. In this expression, the like terms are those that involve the variable p.

Start by identifying the coefficients of the terms that contain p. You have 3p and 2p. When you combine these terms, you add their coefficients:

3p + 2p = (3 + 2)p = 5p.

After combining the like terms for p, you still have the constant term -7 remaining from the original expression. This gives you the overall simplified expression:

5p - 7.

Therefore, the correct simplified form of the expression is 5p - 7. This is why this choice represents the accurate answer.
