Find the exact length of EC.

Step-by-step explanation:

The scale factor is = 4

If AB = 6 then AC = 24   4 times longer.

Using a² + b² = c²    substitute a = 4, b = 24, and c = DC = x

            2208 + 1728 = x²

                3936 = x²

                 4    this is the length of DC  

Now the length of EC is 4 times shorter, so EC =

the reporter's right

step-by-step explanation:

1/4 = .25 / 25%

4 inches will get you 10.16 centimeters, but you can either do 10.1 or round up to 10.2. good luck and hope this : )
