Answer:
x = 1
Step-by-step explanation:
The line of symmetry is defined as the x value of the vertex of a parabola.
To find the vertex of a parabola, we need to convert to vertex form.
Vertex form looks like this:
, where -h is the x value of the vertex and k is the y value of the vertex.
H is also defined as 
where a is the coefficient of x squared and b is the coefficient of the x term.
The coefficient of the x squared term is 1 and the coefficient of b is -2.
Plugging in, we get 
, which is equal to 1. This can then be plugged into the equation as
, but k doesn't matter because all we need is the x-term. Now, our x-term is negative h, which is negative negative one, which is positive one. Therefore, our answer is x = 1.

Answer:
first choice
Step-by-step explanation:
The volume of a rectangular prism is L*H*B.
So the volume of the rectangular prism pictured here is 24*10*8
The volume of a triangle prism is 1/2 *H*L*B.
So the volume of the triangle prism pictured here is 1/2 *6*24*8
The volume of the whole figure is the sum of the volume of the rectangular prism and volume of the triangular prism which is in this case:
24*10*8 + 1/2 *6*24*8.
Answer is the first choice.
(It wouldn't be third because 10 has nothing to with the triangular prism part)
As in which form do u want that in?
