Numbers 9-14 and 20.
Check the examples on page 208 and 209.
The problems are distributive property problems.
However, you may have to simplify the parentheses first.
Example 1-
4(x + y)
Distribute the 4 through the parenthesis.
Answer:
4x + 4y
These cannot go together. One term is an x and the other is a y.
Example 2-
-4(-3 + x)
Distribute the negative 4 through the parenthesis.
Answer:
12 - 4x
This is the final answer. They cannot go together. One term is a constant and the other is an x.
Example 3-
-4(-10 + 3x + 7)
First simplify the parenthesis...
The negative 10 and the the positive 7 are constants and can go together. -10 and positive 7 combine to equal -3.
After simplifying, the problem now looks like this.
-4(-3 + 3x)
The parenthesis have been simplified, now you can use the distributive property.
-4 multiplied by -3 and -4 multiplied by 3x.
This expression is simplified to...
12 - 12x is the final answer.
These cannot go together. One term is an x, and the other is a constant.
