Answer:
Vertex (-2,-9)
zeros: x=1, x=-5
y-intercept: -5
Step-by-step explanation:
When you graph the quadratic equation you obtain the parabola shown in the figure attached.
Find the vertex of the parabola observing the graph, you can that the minimum point of the parabola is at (-2,-9) this is the vertex.
The zeros are the x-intercepts:
x=1; x=-5
And the y-intecept is when x=0 and the parabola cut the y-axis. This is: -5.

Answer:
The measured side is not shown, so i will answer in a general way.
A cube is a 3-dimensional object with 6 square faces.
You know that all the sides of a square have the same length, then is the same for the cube.
To calculate the volume of a cube, we start with the area of the base.
The base is a square of sidelength L (Suppose that L is the length of the measured side)
The area of the base is:
A = L^2.
To find the volume, we must multiply the area of the base by the height of the fire (because the section of the base does not change).
And the height of the cube is also L.
Then the volume is:
V = L*a = L^3
