If N is a positive integer, it must be either even or odd.
If N is odd, then N-1 will be even.
If N is even, then N-1 will be odd.
Either way, when you multiply n and n-1, one of those expressions is going to be an even number, and any number multiplied by an even number is an even number.
Hope this helps! :)
Answer:
48
Step-by-step explanation:
Since there is an absolute value, the answer must be positive. Multiply 2 by 8 since two negatives equal a positive. So, |15-47 + 9 - 8 -17|. Then add and subtract to get the answer. -32 + 9 - 8 -17 = -48. |-48| = 48
1:
10=6
5=3
not sure
2:
triangle=16
circle=27
square=26
3: c
6: .78 per minute
7: they both have the same price one jaut has more ounces
7: they would make 10.56 dollars profit
So, the next two numbers are 55 and 89
So,
1+1=2
1+2=3
2+3=5
Starting at the 1,1 add them together to get the next number which is 2. Then 1,2 add 1+2 to get the next number which is 3. Next, 2,3 add 2+3 to get the next number which is 5
I hope you understand that. I tried to explain it at the best of my ability
