Answer:
4n^2 - 3n + 7
Step-by-step explanation:
Area is length x width. If the width is 5n^2, we have to factor that out of each variable of the area
Area: 20n^4 - 15n^3 + 35n^2
20n^4 divided by 5n^2 = 4n^2
-15n^3 divided by 5n^2 = -3n
35n^2 divided by 5n^2 = 7
So the length is 4n^2 - 3n + 7
4. Percent increase
Because Original Value < New Value
5. Percent
6. Whole
Because it's asking what number that means total.
