• A
• B
• C
• D

Multiple Choice

Match the graph with its inequality.

Remember that multiplication is just REPEATED ADDITION!

Multiple Choice

• x is less than or equal to -2

• x < -2

• -2 < x

• x is greater than -2

For the problem 9(4+3)...

• The 9 is outside the parenthesis so this is the number that needs to be multiplied by EVERYTHING inside the parenethesis

For the problem 2(5+3)

• 2 is the number before the () so you will need to multiply it by the 5 and 3

• (2x5)+(2x3)

Multiple Choice

Use your notes to write this equation in another form...

9(4+3)

• 9(4)+9(3)

• 3(4)+9(3)

• 4(9)+4(3)

Multiple Choice
