AB + BC + CD = AD <em>segment addition postulate</em>
+ 8 + 7 = AD
+ 15 = AD
AD + 60 = 4AD
60 = 3AD
20 = AD
AB = = 
= 5
DE =

CD + DE + EF = CF <em>segment addition postulate</em>
7 + 4 + EF = CF
11 + EF = CF
Answer: 11 + EF
Note: You did not provide any info about EF. If you have additional information that you did not type in, calculate EF and add it to 11 to find the length of CF.

Adding and subtracting property
Answer:
19x+8
Step-by-step explanation:
1) distribute the term outside the parenthesis to each term inside:
4*3x=12x
4*2=8
12x+8-7x
2) 12x+7x=19x
19x+8
Hope this helps!
