Simplify the expression
shown below:
-2(-2x - 4)
Distributive Property 100
Step 1: Make sure expression is in addition form
-2((-2x) + (-4))
Step 2: Multiply outside number into BOTH inside numbers
(-2)*(-2x) + (-2)*(-4)
4x - (-8) = 4x + 8
Distributive Property 100
What mistakes were
made below?
-3(5x + 4)
15x + 4
Distributive Property 200
Step 1: Make sure expression is in addition form
-3((5x) + (4))
Step 2: Multiply outside number into BOTH inside numbers
(-3)*(5x) + (-3)*(4)
-15x + (-12) = -15x - 12
Mistake: sign for number outside parenthesis changed
Mistake: did not fully distribute outside number
Distributive Property 200
What mistakes were
made below?
3(-2x + 3)
6x + 9
Distributive Property 300
Step 1: Make sure expression is in addition form
3((-2x) + (3))
Step 2: Multiply outside number into BOTH inside numbers
(3)*(-2x) + (3)*(3)
-6x + 9
Mistake: changed sign of first number in parenthesis

A family bought four
children food. The kids
all ate two $4 burgers and
three $2 fries.
What expression shows
the family meal cost?
Distributive Property 400
Step 1: Write what you know
People = 4
Item 1 (burger) = $4…. Two eaten per child
Item 2 (fries) = $2… Three eaten per child
Step 2: Use the model below to help find equation
Equation = people * [ (how many)(item price)
+ (how many)(item price) ]
4 [ (2)(4) + (3)(2) ]
