What is the shape that the question below

D

Step-by-step explanation:

Let's just go through it.

No parallel sides A B C (if you believe the diagram) D F

Not regular (and no parallel sides) (if you believe the diagram) B C D F

No Lines of symmetry (that means that if you put a mirror on a line of symmetry) what you see as an image will be the same as what there is in front  of the mirror. C D F

Has a reflex angle. (Just to remind you, it is an angle greater that 180 but less than 360

That lets out everybody but D.

D

Step-by-step explanation:

1. C and G have one set of parallel sides, and E, H, and I have two sets of parallel sides so they can be ruled out.

2. Regular shapes have sides that are all the same length and angles that all measure the same. A can be ruled out in addition to I which was already ruled out.

3. B can be ruled out now.

4. The only one with a reflex angle (greater than 180 degrees) is D.

x² + 11x + 18 < 0  

[-11 ± sqrt(121 - 72)]/2 = (-11 ± 7)/2  

solution: (-9, -2)
