Best ResponseYou've already chosen the best response.2you multiply ALL of `252x` by `x`

jim_thompson5910
 one year ago
Best ResponseYou've already chosen the best response.2so you'd say (252x) * x

jim_thompson5910

Best ResponseYou've already chosen the best response.2you have them both correct

Destinyyyy
