False!
Counter-example
4 possible multiples of 6 are
6, 12, 30, and 42
their sum is 90
but 90 is not divisible evenly be 12, so the statement is false
Ashley claims that the sum of four multiples of 6 will be a multiple of 12. Is Ashley's conjecture reasonable? If not provide a counter-example.
Prove that the perimeter will be even for any rectangle with natural number side lengths.

for the perimeter, since
p = 2(length+width)
p is even, since it is a multiple of 2.
p = 2(length+width)
p is even, since it is a multiple of 2.
