3( 5x - 9 ) =

3*5x - 9*3 =

3(5x - 9) Multiply every term inside parentheses by 3. 3(5x) = 15x 3(-9) = -27 15x - 27
by Level 1 User (460 points)
To get the distributive property to expand 3(5x - 9), first mulitply 3 x 5. 15, so you add the x next to 15, so 15x. Then multiply 9 x 3 to get 27, so 15x - 27. Since we don't know what the x is, that is the answer.
