Answer:
No, but all parallelograms are quadrilaterals.
Step-by-step explanation:
Take a trapezoid, for example. A trapezoid is a quadrilateral because it has 4 sides, but it does not contain 2 sets of parallel sides thus making it not a parallelogram.
Answer: there needs to be more infomation
Step-by-step explanation:
The centroid divides the median into a 2:1 ratio. So, 9x-9=4x+16. We solve and get x=5. Therefore, OB is 36, and BE is half, 18.
Follow pemdas: start with distributing the -2 unto the (-12x+8) which will equal 24 -16 which is 8. Then add the 8 from the other side which is 16. Add like terms on the other side which is 24x. Then divide by 24. You get 2/3 when simplified. Hope this helps:)
