I know this is the right answer can you guys just explain it in the simplest way that I would understand, I'm on Thanksgiving break so my teacher isn't available at the time. I will give the brainliest to you if you help me understand it, please.

The answer is the first one.

Step-by-step explanation:

If x oranges were sold on Thursday, what is two times that? Well, 2*x is the same thing as 2x. When a variable and a number a put together, that means it is being multiplied. So, on Thursday x oranges were sold, and on Friday twice as much as that were sold. So, at the bottom, in the red part wold be x and 2x. The blue bar is the total number of oranges sold, which is 108.

if the eqn of the parabola is f(x) = (x-4)(x+2), we need to mult. this out to find the coordinates of the vertex.

then f(x) = x^2 + 2x - 4x - 8, and f(x) = x^2 - 2x - 8.

one way in which you can find the vertex is to calculate x = -b / (2a).   here, that comes to

        )

x = = 1.   f(1) = 1^2 - 2(1) - 8 = - 9.   vertex is at (1, -9).

        2(1) 

find another point on the curve:   let x=0, for which y=-8.   then (0, -8) is on the curve.   plot the vertex and this point and draw a smooth parabola thru both.

hope this
