Quiz : 

Question 1: Find x

Question 2: What is the length CB if FE is 3cm ? 

Question 3: What is the scale factor?

Quiz: Answers : 

Question 1. Find x :

       1.) set the equation up.

       2.)  X  = 7

            23    14

       3.) 14 x = 161

       4.) 161/14 = 11.5

Answer: x = 11.5 ( the ratio is 1:2)
