Recall the secant-tangent theorem, and you have
EA^2 = EC*CD
12^2 = 8*(x+10)
and now ED = EC+CD = 8+x+10
I suspect a typo somewhere in the murk above
Since it turns downwards (the shape on an "n", it is a maximum point)
Maximum point occurs at (-2, 1)
Answer: (B) (-2, 1) maximum

Answer:
(5r - 20)
Step-by-step explanation:
