8 7 
???
AB + BC + CD = AD <em>segment addition postulate</em>
+ 8 + 7 = AD
+ 15 = AD
AD + 60 = 4AD
60 = 3AD
20 = AD
AB = = 
= 5
DE = 
= 
= 4
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.
Answer:D ( if you add +4 to the (x + 3)^2)
Step-by-step explanation:
Parent function is f(x) = x^2
A translation 3 units left gives y = )x + 3)^2
- and 4 up gives y = (x + 3)^2 + 4 - vertex form.
Standard form :
y = x^2 + 6x + 9 + 4
= x^2 + 6x + 13.
Solving: (5)(3 - 1) + 4
Step One: Subtract 1 from 3 which is 2
<span><span>5<span>(<span>3 − 1</span>) </span></span>+ 4
Step Two, Multiply 5 by 2 which is 10</span><span>=<span><span><span>(5)</span><span>(2) </span></span>+ 4
Step Three, Add 4 to 10 which is 14</span></span><span>=<span>10+4

Answer:
(A)14
Hope this helps!

Hopefully I’m correct but I think it is 7% because 50 -43 equals 7%
