Question

Gary applied the distributive property using the greatest common factor to determine the expression that is equivalent to 66 + 36. His work is shown below.

Factors of 66: 1, 2, 3, 6, 11, 22, 33, 66
Factors of 36: 1, 2, 3, 4, 6, 9, 12, 18, 36

66 + 36 = 3 (22 + 12)

What statement best describes Gary’s error?
Gary did not use correct factors for 66 in the equation.
Gary did not use correct factors for 36 in the equation.
Gary did not use two equivalent expressions in the equation.
Gary did not use the greatest common factor in the equation.

Answer 1

Answer: Gary did not use the greatest common factor in the equation.

Step-by-step explanation: Gary did not use the Greatest common factor because the greatest common factor would be 33

Answer 2

Gary did not use the greatest common factor in the expression.

Explanation:

Both factors of 36 and 66 are correct.

Gary also used equivalent expressions. I hope this helps.
