Answer:
A D and E are the answers
Step-by-step explanation:
The general formula is n * CD so all you do is multiply n times the original length.
A is true. 3/2 * 12 = 36/2 = 18 True.
============
B is not true 4*12 = 48 not 3
B would be true if n = 1/4
1/4 * 12 = 3
============
C is not true 8*12 = 96 not 20
============
D is true 2 * 12 = 24
============
E is true 3/4 * 12 = 36/4 = 9
A D and E are the answers
