Answer:
3 roots
Step-by-step explanation:
(9x+7)(4x+1)(3x+4)=0
x=-7/9 or - 1/4 or - 4/3
I just kind of sat here playing with numbers i dont really know a shortcut but the answer is 10 chickens and 15 rabbits
10*2= 20 each chicken has two legs so thats 10 heads 20 legs
15*4=60 each rabbit has four legs so thats 15 heads 60 legs
15+10=25 heads
20+60=60 legs
60 minutes is an hour , you haven't given out what the 15, 30 and 60 are , and the 1 , 2 and 4 are(minutes or hours?)
Its B
Hope this helps!
