X= 12(.7)^x(exponent)
x is the doll you are on. For example if your looking for the height of the height of the doll after the 12 in. one then x=2 and so on

lana66690 [7]
Answer:

EC = 35

Step-by-step explanation:

The whole entire line measures 49

DB measures 30

49 - 30 = 19 or ED

But we’re looking for EC so…

19 + 16 = 35

EC = 35
