Answer:
3ny
Step-by-step explanation:
For this problem, the price of a widget is represented by 'n' amount of dollars. Additionally, the store was stocked with 4y widgets.
To find the total cost of the widgets sold, we will use the information that at the end of the day, the store only had y widgets remaining.
From here we can say the following to represent the total cost of the widgets sold:
cost = n * (4y - y)
cost = n * (3y)
cost = n3y
You can rewrite this cost to be 3ny as in the answer choice.
Cheers.

Answer:

Step-by-step explanation:
The area of the rectangle can be written as:

here, x is one side length, and h is the other side length. This area is said to be equal to 54 square meters.

The perimeter of a rectangle can be written as:

To express perimeter only in terms of x (in other words making it a function P(x)). we need to replace h. And this can be done by using the equation of area that we derived earlier.


now we can substitute this 'h' into our equation of the perimeter.


and voila! we have expressed P in terms of x only.
this can be written as P as a function of x as:

If you are finding the y-intercept of the values, it would be D no solution because the slopes are the same. Since the lines are parallel, there would not be a solution.
