Answer:
D. III and IV only
Explanation:
III and IV only because those are the only true statements.
III: 5+6= 11 is true.
IV: 17 is greater than 2 or 6 is true.
I: This one is false because of 9-2=11, which is not true. 9 minus 2 equals 7, not 11.
II: positive 4 is not less than negative 4.
Hope this helps!
