Answer:
Option A. 
Step-by-step explanation:
we know that
The area of the irregular figure is equal to the area of two trapezoids
The area of trapezoid is equal to

where
b1,b2 are the parallel bases
h is the perpendicular distance between the parallel bases
<u>Find the left trapezoid area</u>

<u>Find the trapezoid area on the right</u>

The area of the irregular figure is

She has 15 left because she had 28 then she at 3 which is now 25 then she gave 5 away which is 20 then she gave 5 more away which is 15. So she ends up with 15
The coordinates of B would be C. (4, -8)
I got this because when reflecting over the x axis, the only value that changes is the y value. If you graph it out, the y value is the opposite while the x is the same.
Hope this helps!
Start by pulling out a three
y = 3(x^2 - x - 2) Now it is much easier.
y = 3(x - 2)(x + 1)
