In 4 years you pay interest of 4000 and if you finish pay the loan in two years you pay only 2000
Answer:
x^4 + x^3 + 13x + 5
Step-by-step explanation:
We know that the perimeter is the all the sides added up together. Generally, you have

, where l is length and w is width.
For a square, all sides are of the same length, so you can write

, where x is any side.
If the smallest perimeter is 14, then

, so x is 3.5. If the largest perimeter is 72, then

, so x is 18.
Therefore, you have 3.5 ≤ x ≤ 18.
You are counting by 10s so the answer is 40,50,60,70,80
the complete sequence: 10,20,30,40,50,60,70,80,90,100
