When the integer z is divided by 12, the remainder is 3. Which of the following, when divided by 12, will have a remainder of 6 ?
I. 2z
II. 6z
III. 4z + 6	Select the correct option:
A) I only B) II only C) III only D) I and II only E) I, II, and III
is it E.   z= 12*a + 3   2z = 12*2*a + 6   6z = 12*6*a + 18 ( 18 = 12+6)   4z + 6 = 12*4*a + 18 (18 = 12 + 6)
<result>E</result>
