Use prime factorization to find the GCF (greatest common factor) of the following sets of numbers. Show the steps you used to find the GCF. 1) 18: 20: GCF: 15: 25: GCF: 40: 32: GCF: 12: 22: GCF: 10: 20: GCF: 9: 16: GCF: 30: 15: GCF: 15: 35: GCF: 14: 28: GCF: 24: 8: GCF: 45: 27: GCF: 36: 42: GCF: 2)3) 4) 7) 10) 5) 8) 11) 6) 9) 12)

i dont understand the question? ?

step-by-step explanation:

the answer is a if my teacher taught me correct

its kinda hard to answer this when we dont have all the information that we need.

answer:

at time x=0 we have 1000, at time x=1 we have 2000, at time x=2 we have 4000.  

so that's an initial value of 1000 and a ratio of 2,

y = 1000 (2^x)

hope this !
