Answer:
x=150
Step-by-step explanation:
Since f is flat, that means that the total degrees will equal 180°.
Therefore, because of the 60° and (x-30)° angles being supplementary angles,
will equal 180.

Answer:
The dependent variable is d
Step-by-step explanation:
Because the dependent variable depends on the independent variable in this case the amount of money she gets is depended on how many hours she work
The correct answer is 4a^2 + 3ab
In order to find this, we can write the equation out as described and then follow the order of operations.
3a^2 - 2ab + 3b^2 - (-a^2 - 5ab + 3b^2) ----> Distribute the negative
3a^2 - 2ab + 3b^2 + a^2 + 5ab - 3b^2 ----> Combine like terms
4a^2 + 3ab
