Q5.

A student simplifies 6(y + 2) + 3y as 9y + 2. Which statement best explains the student's error?

  1. A) The student did not multiply 2 by 6; the result should be 9y + 12.
  2. B) The student multiplied y by 6 incorrectly; the result should be 12y + 2.
  3. C) The student should subtract the constant; the result should be 9y − 12.
  4. D) The student should not combine 6y and 3y; the result should be 6y + 3y + 2.

Q6.

  1. A) 8b + 7
  2. B) 10b + 7
  3. C) 8b − 7
  4. D) 8b + 11

Q7.

Compare 4(n + 3) + 2n and 3(2n + 4). Which statement is correct?

  1. A) The expressions are not equivalent because their variable terms are different.
  2. B) The expressions are equivalent because both simplify to 6n + 12.
  3. C) The first expression is greater because it simplifies to 8n + 12.
  4. D) The second expression is greater because it simplifies to 6n + 16.

Q8.
