Answer: C

Explanation:

Using the Triangle Inequality Theorem, the sum of two sides must be greater than the third side.

BD + DC > BC and DC + BC > BD and BD + BC > DC

x+3 + DC > 9 and DC + 9 > x+3 and x+3 + 9 > DC

-3 -3

DC + 6 > x

x < DC + 6

If x + 3 + DC > 9, then obviously x + 3 > 9

Similarly, if x < DC + 6, then obviously x < 6
