Extracurricular activities are an essential part of a great college application. They can really help you to stand out in the eyes of an admissions officer. While it is important to demonstrate that you do have a life outside of school, some activities are viewed more favorably than others. It is also essential that you present your activities in the proper way to ensure that you don't come across as either desperate or uninterested. You can learn more about extracurricular activities and their effect on college applications here.
6/5 Equations and Factoring
We can simplify the equation like so
If we look at the fully factored form of the equation we can see that we are going to multiply whatever we have in the parenthesis by 5. That means that our result must be a multiple of 5. Now we look at the answers below.
You can see that answer (B) matches our prediction exactly. As I mentioned earlier, there is one other way to solve this problem. We can pick numbers for X. The easiest number to pick for X is 1. If we do that the formula becomes
In this case, our formula gives us the number 5. Since we need an answer that must be true, we can eliminate any answers that do not fit and in this case only (B) works (don't forget that step 5 of the Knowsys math method is to loop back and verify that your answer matches the bottom line). Picking numbers can be a great strategy if you get stuck on a problem but it is generally faster to solve the problem by writing out the formula.
The correct answer is (B).
