Darian wants to build a regulation size pool table that is 9 feet in length. the plans he ordered are 18 by 36 inches. what is the scale factor of the dilation he must use to build the regulation pool table?

  3

Step-by-step explanation:

Darian's plans are 3 feet long, and they're for a table 9 feet long. The scale factor is 9/3 = 3. That is, he must multiply the plan size by 3 to get the actual size.

A scale factor is usually expressed as a fraction: (model size)/(real size). Here, it looks like you want a dilation factor that is (real size)/(model size).

y/x=18
