2n-3 = 9
solve for n by first adding 3 to both sides
2n = 12
divided both sides by 2
n = 6
37 Fit the cubic: Un = (2n3 - 9n2 + 16n + 6)/3 for n = 1, 2, 3, ...
There are many possible answers. One possibility is Un = (2n3 - 3n2 + n + 24)/6
9.
2, which equals 54. 3, which equals 36. 4, which equals 27. 6, which equals 18. 9, which equals 12. 12, which equals 9.
9 feet equals 3 yards.

If x=9, x=9
9-8 equals = 1
9 out of 15 equals 60%
No! It equals 15, but 9-6=3.
