Answer:Your left hand side evaluates to:
m+(−1)mn+(−1)m+(−1)mnp
and your right hand side evaluates to:
m+(−1)mn+(−1)m+np
After eliminating the common terms:
m+(−1)mn from both sides, we are left with showing:
(−1)m+(−1)mnp=(−1)m+np
If p=0, both sides are clearly equal, so assume p≠0, and we can (by cancellation) simply prove:
(−1)(−1)mn=(−1)n.
It should be clear that if m is even, we have equality (both sides are (−1)n), so we are down to the case where m is odd. In this case:
(−1)(−1)mn=(−1)−n=1(−1)n
Multiplying both sides by (−1)n then yields:
1=(−1)2n=[(−1)n]2 which is always true, no matter what n is

24/5=20/5+4/5=4+4/5
4/5 times 60=48
4hr and 48 mins
24hr=60*24mins=1440mins
1440/5=288mins per night
A. 4 and 4/5 hour or 24/5 hours
B. 4hr and 48 mins
C. 288 mins
Answer:
Step-by-step explanation:
∠CBA + ∠ABD = 180 {linear pair}
2x - 6 + x +1 = 180
3x -5 = 180
3x = 180 +5
3x = 185
x = 185/3
x = 61 2/3
