<span>(8r^6s^3 – 9r^5s^4 + 3r^4s^5) – (2r^4s^5 – 5r^3s^6 – 4r^5s^4)
= </span><span>8r^6s^3 – 9r^5s^4 + 3r^4s^5 – 2r^4s^5 + 5r^3s^6 + 4r^5s^4
= </span>8r^6s^3 – 9r^5s^4 + 4r^5s^4 + 3r^4s^5 – 2r^4s^5 + 5r^3s^6
= 8r^6s^3 – 5r^5s^4 + r^4s^5 + 5r^3s^6
Hope it helps
Answer:
10 rounds.
Step-by-step explanation:
Let x represent number of rounds around the field.
We have been given that the distance around our playing field is 300 meters long. So distance covered in x rounds would be meters.
We are also told that your coach wants you to run 3 kilometers. Let us convert 3 km in meters.
1 km = 1000 m
3 km = 3*1000 m = 3000 m
Now, we will equate total distance covered in x rounds by 3000 as:
Therefore, you need to run 10 times around the field.
