A, because: 20x10 1/2=210
And 20x11 1/4=225
And 225-210=15
So thats the answer.
3 x3 = 9 4 x 3 =12 6 x 2 = 18 3 x
The answer is 36,00
This is because 5x 60 gives you the amount in a minute
Then you take that answer and multiply it by another 60 to give you the number per hour
Then that number times 2 to give you the amount every two hours
Answer:
x(x - 2)
Step-by-step explanation:
x² - 2x ← factor out x from each term
= x(x - 2)
