Answer:
x=5
Step-by-step explanation:
2x – 4 = 6
Add 4 to each side
2x – 4 +4= 6+4
2x = 10
Divide each side by 2
2x/2 = 10/2
x = 5
If we set the equation equal to 0, we can factor it to find its roots:
x² + 4x + 4 = 0
(x + 2)(x + 2) = 0
x = -2
This graph has one root, a double root, at -2. This means that a single point, which must be the vertex of the parabola, touches the x-axis at (-2, 0)
Radius- 5
The radius is half, so if you want to find the radius, you have to see what if half of the diameter, which is 10. So 10 divided by 2 is 5 which is the radius. Easy.
