Answer:

18

Step-by-step explanation:

Thanks to the triangle proportionality theorem, we know that [tex]\frac{AD}{DB}=\frac{AE}{EC}[/tex] Input the numbers we know. [tex]\frac{6}{1} =\frac{x}{3}[/tex] Now we need to solve for x by cross multiplying. 6 times 3 is 18 and then 18 divided by 1 is simply 18.
