Question

If a and b are even integers and c is an odd integer, which of the following would be an odd integer?

a + b + c
ab - bc
a x b x c
b x c
c (a + b)

Answer 1

a + b + c

Answer 2

sub in values and try for yourself?
ex. a + b + c
4+4+3= 11

Answer 3

but how'd u get that bro?

Answer 4

You get it by doing exactly what they just did. Subbing in values.

Answer 5

by thinking, just for instance make a and b = to 2

Answer 6

Put there is a more general rule:

Even + Odd = Odd

Answer 7

and amke c 3, just solve them in your head

Answer 8

make*

Answer 9

But* not Put

Answer 10

Ok let a =2x
b =2y
c= 2m+1
Now tthe sum a+b+c must be written in the form 2n+1
Thus
a+b+c =2x+2y+2m+1
=2(x+y+m)+1 Now let x+y+m =n
=2n+1
W/c is odd.
