Answer:
x=3 , x=-3
Step-by-step explanation:
Add 9 on both sides
To remove base 'e' we take ln on both sides
Both sides have ln , so we make the terms equal
Take square root on both sides
x=3 , x=-3
A conjecture and the paragraph proof used to prove the conjecture are shown.

Answer with explanation:
Given: E is the mid point of DF.
Prove: 2 DE=D F
Proof with explanation:
It is given that is mid point of
.
1.→
So,
-------------------------By Definition of mid point
2.→ DE=E F----------------Segment Congruence Postulate
3.→DE+E F=D F ----------------Segment Addition Postulate
4.→DE+DE=D F-------------By Substitution
5.→Simplifying gives
2 DE=D F
