Since E is a midpoint, we can set de and ef equal to each other to find the value of x. 

6x = 3x + 6
3x = 6
x = 2

Then we can plug in x=2 and find that both de and ef are 12. Then since E is the midpoint of df, we can add de and ef to find the value of df. 

12 + 12 = 24

so company A charges less when renting for 6 days
=================
for 10 days...
company A :
C = 35(10) + 15 = 365

company B :
C = 42(10) + 10 = 430

REAAAALLLLY NEED HELP
pashok25 [27]
If you think about it, the question is asking us to find the greatest common factor, or GCF, of the two numbers, 24 and 18. 
First, find all of the factors of 24. 
The factors are: 1, 2, 3, 4, 6, 8, 12, 24 
Next, find the factors of 18.
The factors are: 1, 2, 3, 6, 9, 18 
List out all of the factors that both of the numbers have. 
The factors are: 1, 2, 3, 6
Whichever is the greatest of these numbers is the GCF. 
The GCF is 6, so the greatest number of groups he can make and still be able to win is 6. 
Hope this helps!
