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)

Answer:
x = 0, π/4, π, 7π/4
Step-by-step explanation:
sin(2x) = √2 sin x
Use double angle formula.
2 sin x cos x = √2 sin x
Move everything to one side.
2 sin x cos x − √2 sin x = 0
Factor.
sin x (2 cos x − √2) = 0
Solve.
sin x = 0, cos x = ½√2
x = 0, π/4, π, 7π/4
Answer:
Width is 24, length is 40
Step-by-step explanation:
64 can be split into 8 groups of 8, and the 8 groups can be split into 3 and 5. Then, take 3 x 8 for the width and 5 x 8 for the length, and you have the answer! I wish to you best of luck!
