Answer:
Step-by-step explanation:
Calculate the volume of a cone by its base and height with the equation volume = 1/3 * base * height. You can calculate the height of a cone from its volume by reversing this equation. Triple the volume amount. For this example, the volume is 100.
i dont have much time to go through all the work but i can tell you that since its a 90 degree angle, your equation would be 90=15x-2+7x+4. Once you get the value of X plug that into each of the equations. For example if your x value was 2 you would do 15(2)-2. Thats just an example.
Answer:
you can divide the answers by the time duration of the exam and get your answer
Step-by-step explanation:
You can do prime factorization then find common factors to factor out.
6m² - 15m
2·3·m·m - 3·5·m
Both terms have 3·m so we can factor it out:
3·m (2·m - 5)
So that would be 3m (2m - 5)
