the product of two consecutive odd numbers is 399. what are these numbers? Answer by Alan3354(69443) (Show Source):
You can put this solution on YOUR website! the product of two consecutive odd numbers is 399. what are these numbers?
-----------
If you factor 399, you find it has a factor of 19.
399 = 19*21
--------------
If you do it the "hard way"
x*(x+2) = 399
Now you have to factor 399 anyway.
--> 19 & 21
---------------
Another way: is almost 20, the middle of the 2 numbers.
--> 19 & 21
