Distributive Lesson

Combining + Distributive

Don't Forget:

• We start an IB Project next week - way to boost your grade!

• We have a test on Expressions on Friday - do you have the notes?

• Spiral Reviews are WEEKLY - are you doing them? why not?

Yesterday

We practiced combining like terms

Today

We will discuss how to combine like terms with the distributive property

Remember, Distributive Property...

• Looks like this 5 ( x + 6 )

• Multiply everything on the insides of the parentheses by the number on the outside of the parentheses.

• Answer: 5(x+6) = 5x+30

Multiple Choice

5(a + 6)

• 5a + 6

• a + 30

• 5a + 30

• 5a - 30

Multiple Choice

2(c - 8)

• 2c - 16

• 2c + 16

• 2c - 8

• c - 16

Multiple Choice

Simplify the expression

11(9 + d)

• 99 + d

• 20 + 9d

• 20 + d

• 99+11d

Multiple Choice

8(x + 5)

• 8x + 13

• 8x + 5

Multiple Choice

Simplify the expression:

• 6h + 9c + 2

• 6h + 9c + 6

• 2h + 3c + 6

• 5h + 6c + 5

Multiple Choice

Simplify the expression:

6(x - 3 + 5y)

• 6x + 18 - 30y

• 6x 18 30y

• 6x + 18 + 30y

• 6x - 18 + 30y
