Answer: A
Step-by-step explanation:
- Open circle means that x does not equal that number. For example, the open circle on C is on 8, so that shows x is not equal to 8.
- Closed circle means that x does equal that number. For example on A, there is a closed circle on 8, so x could equal 8.
First, we need to solve the equation.
- Subtract 200 frim 1200 -> 125x ≥ 1000.
- Divide 125 from 1000 to isolate the x -> x ≥ 8
So, that means x is bigger than or equal to 8.
The answer is: 2(m+1)
First combine like terms.
<em>we do 6m-4m which is 2m</em>
2m+2=?
Second we factor. We notice that both terms have 2.
2(m+1)
<em>by distributive law, the 2 is distributed to m and 1.
