We know that
[volume of a cube]=b³
where
b------> is a side length of a cube
for b=5 in
[volume of a cube]=5³--------> 125 in³
the answer is 125 in³
It could either be 11:9 or 11.../9...
(The dots stand for what the problem is talking about,for example 11 hot dogs per $9
The answer is (4) because you multiply the like terms in the equation. 5*7=35 and 3i*2i=6i.
Answer is (4)
Answer:
2
Step-by-step explanation:
(6+2)x 12 =96
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
