Did you type something in wrong?
Step-by-step explanation:
9+4+15=28 total balls
9=total red balls
total red balls/total balls= probability of pulling out one red ball
9/28
9÷28=32.1%

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)
