Combine Like Terms or Distributive Property

When doing the distributive property, which of the following is true?

• You only distribute to the first two terms in the parenthesis

• You first multiply the variables, then the coefficients 

• You want to multiply the coefficients, then the variables, ad then combine any like terms

• You will never have exponents with variables when you distribute

3(3x +1)

• 9x +3

• 3x + 3

• 12x

• 9x + 1

Simplify the expression: 2x + 1 + 7x
