Distributive Property Day 1
Distributive Property allows you to distribute a factor outside a
parenthesis to the addends/subtrahends inside the
parenthesis.
In-Ticket 1.Solve: ( 3^2 – 8÷2)4 2. Evaluate if x=6, y=5, and z=10
7x – (5z – 4y)
3. Identify the Property (5+3) x 2 = (3+5) x 2
4.Translate the phrase Six times the difference of four and a number
Example #1Using order of
operations5(6+1)5 x 735
Using distributive property
5(6+1)5 x 6 + 5 x 1 30 + 5 35
Example # 2Using order of
operations7(3 – 2)7 x 17
Using distributive property
7(3 – 2)7 x 3 – 7 x 2 21 – 14 7
What about 5(a+3) or 7(6+x)
Can you add a and 3?Can you add 6 and x?
Must use Distributive Property to help simplify Algebraic
ExpressionsTo Simplify Algebraic ExpressionsStep 1: Get rid of ALL grouping
symbolsStep 2: Do ALL possible operations
This includes combining like terms(Addition/Subtract)
Example #3
5(a+3)5 x a + 5 x 3 5a + 15
Example #4
7(6+b)7 x 6 + 7 x b 42 + 7b
