Step-by-step explanation:
Let the a be the side length of the square in units.
The perimeter of a square is
It is given that a square has a perimeter of 12x+52 units. Substitute P=12x+52 in the above formula, to find the expression that represents the side length of the square in units.
Divide both sides by 4.
Therefore expression 3x+13 represents the side length of the square in units.

Answer:
7,200
Step-by-step explanation:
Let's start by calculating how many students the university accepts. The problem says they accept 60% of the students. 60% as a decimal is 0.6. To calculate 60% of something, you multiply .60 by whatever quantity. In this case, it would be the students.
Number of accepted students = = 18,000
The university accepts 18,000 students.
Now, the next problem is that of those accepted students, we need to find out how many actually enroll. The problem says they accept 40% of the accepted students. Applying the same principle,
Number of enrolled students = = 7,200
The number of students that actually enroll is 7,200.
Alternatively, would give you the same result.
Combining the pieces together, we are asking for 60% of 30,000. Then getting 40% of that 60%.
