k, n - integers
2k+1 - an odd integer
2n+1 - another odd integer
The product of them:
(2k + 1)(2n + 1) =
= 4kn + 2k + 2n + 1 =
= 2(2kn + k + n) + 1
The product of integers (2kn) is integer
and the sum of them (2kn+k+n) also is integer
So (2k + 1)(2n + 1) = 2(2kn + k + n) + 1 is an odd integer
Answer:
total marbles in the box is 600
Answer:
D. They are not commutative, because f(g(x)) and g(f(x) are not equal.
Step-by-step explanation:
I guessed and got it right xD
C= number of children tickets
a= number of adult tickets
In the equation, $9.50 per ticket must be multiplied by each c and a in order to calculate the total.
($9.50 * c) + ($9.50 * a)
since each term has $9.50 in it, we can pull out the common $9.50 in each
$9.50(c + a)
this expression now means that we must multiply $9.50 by c and then multiply $9.50 by a (using the distributive property)
ANSWER: $9.50(c + a) - the second choice down
Hope this helps! :)
