Answer:
The answer is that the vertex is: (1, 0)
Step-by-step explanation:
Use the "Completing the Square Method":
(x - h)^2 - k = 0, the vertex is (h, -k)
Complete the square:
x^2 + 2x + 1 = 0
x^2 + 2x = -1
(2/2)^2 = 1, add 1 to both sides of the equation.
x^2 + 2x + 1 = -1 + 1
(x + 1)^2 = 0
(x + 1)^2 - 0 = 0 (Just to put a placeholder in for he -k)
The vertex is (1, 0)

<h3>Answer:</h3>
17
<h3>Explanation:</h3>
The median segment (HJ = 5x+2) has a length that is the average of the lengths of the other parallel segments, (KL = 4x+1, and NM = 27). Writing this relation as an equation, we have ...
... 5x + 2 = (4x + 1 + 27)/2
... 10x + 4 = 4x + 28 . . . . . . multiply by 2, collect terms
... 6x = 24 . . . . . . . . . . . . . . add -4x-4
... x = 4 . . . . . . . . . . . . . . . . . divide by 6
Then the length of KL is ...
... KL = 4x +1
... = 4·4 +1 = 17
