The actions that prove that the quadrilateral is a parallelogram are:
- Use the slope formula on each side of the quadrilateral and show that opposite sides have the same slope.
- Use the distance formula on each side of the quadrilateral and show that opposite sides have the same length.
<h3>
Quadrilaterals</h3>
Quadrilaterals are polygons that have four sides and four corners
<h3>Parallelograms</h3>
Parallelograms are quadrilaterals that have parallel and congruent opposite sides
For the quadrilateral to be a parallelogram, then the opposite sides must be congruent.
This can be proved using the distance formula
Also, for the quadrilateral to be a parallelogram, then the opposite sides must be parallel.
This can be proved using the slope formula
Hence, the possible actions are (a) and (b)

3.4 hours. The efficiency of a worker is the amount of work divided by time needed. The efficiency of Sanjay alone is 500/6, and the efficiency of Felipe alone is 500/8. When they work together, their combined efficiency is 500/6+500/8=3500/24. Therefore, they need 500/(3500/24)=24/7=3.4 hours.
The line underneath the inequality line(arrow) means p is less than OR EQUAL to 21.
