Put your information into a ratio
14 : 70 (wire : cost)
Change the amount of wire to 9
14/14 : 70/14
1 : 5

9: 45
Therefore 9 inches of wire costs 45 cents :)

Answer:
Option B: x > 0
Step-by-step explanation:
Option A is wrong because

Option C is wrong because 1 will suffice this inequality. 
Option D is wrong because any value in the root has to be greater or equal to 0 (otherwise, it's imaginary number). -1 will give the latter root a value of root-(-3).
Leaving us with only option B, which is the right answer.
The second one, and the two last should be the right answer,
Hope this helped:)
