Let a, b be two odd integers. Then both can be written as
a=2k-1, k is an integer
b=2m-1, m is an integer
So,
a-b=2k-1-(2m-1)=2k-2m-2=2(k-m-1)
Since, k and m and 1 are all integers, then (k-m-1) is also an integer. Hence, 2(k-m-1) is an even integer.
Thus, a-b is even.
Looks about either 38 or 52
Answer:
26
Step-by-step explanation:
(21+31+36+28+26+x)/6=28
21+31+36+28+26+x= 28×6
142+x =168
x=168-142
x=26
Answer:
Step-by-step explanation:
hello :
g√ 108 =√ 3/g means : g² = √ 3/√ 108
g² = √(3/108)
g² = √(1/36)
g² = √(1/6)²
g² = 1/6
g = 1/√6 or g = - 1/√6
I think the correct answer is D. Or if not is B.
