Answer:
n+4≤13
n-(-6)<9 or -6-n<9
68-17≤n in this situation n can be no greater than 51 because he has AT THE MOST 51 envelopes to address.
Step-by-step explanation:
Step-by-step explanation:
4x2 - 25b2
We can solve it by the squares so
(2x - 5b) (2x + 5b)
2) x2 - 81
The same case is here so
(x - 9) (x + 9)
84 cents a pound divide 2 1/4 by 1.89 equals 0.84
A^7. "A" raised to the power of 7 would be the exponential form. hope this helps.
