Answer:
![1+\frac{-63}{x^2-1}](https://tex.z-dn.net/?f=1%2B%5Cfrac%7B-63%7D%7Bx%5E2-1%7D)
Step-by-step explanation:
If you foil this equation you will get:
![\frac{(x+8)(x-8)}{(x+1)(x-1)}](https://tex.z-dn.net/?f=%5Cfrac%7B%28x%2B8%29%28x-8%29%7D%7B%28x%2B1%29%28x-1%29%7D)
And by dividing it, you will get;
![1+\frac{-63}{x^2-1}](https://tex.z-dn.net/?f=1%2B%5Cfrac%7B-63%7D%7Bx%5E2-1%7D)
That is your answer!
<u>Complete Question</u>
In triangle ABC: AC=10
, AB=5., Angle C = 30 degrees.
In Triangle DEF: ED= 7.5
, DF=15, Angle F =30 degrees
, Angle E = 90 degrees.
Answer:
A, D and E
Step-by-step explanation:
The diagram is drawn and attached below.
- Triangle ABC is similar to Triangle DEF. (Option E)
Writing it backwards:
- Triangle CBA is similar to Triangle FED. (Option A)
Also,
- Triangle BAC is similar to EDF. (Option D).
Therefore, A, D and E are the similarity statements that describe the relationship between the two triangles.
