• Because they are both even numbers.

• Because they are both greater than 10.

• Because they are like terms.

What is the distributive property formula?

• a + b = b + a

• a * (b + c) = ab + ac

• a - b = b - a

• a / b = b / a

How can 11X + 9X be rewritten using the distributive property?

• 11X + 9X

• 11X * 9X

• X + 11 + 9

• X * (11 + 9)
