Multiply 1.5 and 11, replacing 11 for b and you get 16.50
It looks like you are trying to factor a quadratic. So you are looking for the numbers that when you multiply them, you get the top number (100), but when you add them you get the bottom number (-20).
Those two numbers are -10 and -10.
Hope that helps!
Answer:
105 is the least common denominator
Step-by-step explanation:
Since 7, 5 and 3 are all prime.

Since we need to find the number of ways they could enter first, second and third place, (I can't demonstrate, but you should get the idea) take 8, 7 and 6 and multiply them, 5-1 we don't need, we just need 8, 7, and 6, multiply those three numbers and you get 336, there you go, 336 ways to organize all 8 girls in first, second and third place, hope this helps
