The GCF of 9s and 63s^3 is 9s.
You could have one No. 9 or a handful of No. 9s
9s + 7 = -11 9s = -18 s = -18/9 s = -2
The GCF is 9s.
googol - 1 = 10100 - 1 = 9,­999,­999,­999,­999,­999,­999,­999,­999,­999,­999,­999,999,­999,­999,­999,­999,­999,­999,­999,­999,­999,999,­999,­999,­999,­999,­999,­999,­999,­999,­999,­999,­999 (that's one hundred 9s).
Five 9s:(99 x 9 + 9) / 9 = 100
Since 9s is a factor of 36s, it is automatically the GCF.
The equivalent of 7s plus 2s is 9s.
You have to combine equal terms. -5r-9s+9r+3s-6 = -5r+9r-9s+3s-6 = 4r-6s-6
The next year after 1999 that will have three 9s in its title will be 2999.
