There are a number of ways to show whether a quadrilateral placed on a coordinate plane is a parallelogram or not. Here are a few ways:
1. Show that both pairs of opposite sides are congruent.
2. Show that both pairs of opposite sides are parallel
3. Show that a pair of opposite sides are congruent and parallel
4. Show that the diagonals bisect each other.
In this activity, we will use the Distance, Midpoint and Slope Formulas that we learned in Algebra 1 to show congruent, bisected and parallel segments.

Answer:
You earned $45.50 taking care of your neighbor's dog.
Step-by-step explanation:
Add 38.75 + 25. You get 63.75.
Subtract 63.75 - 18.25. That is how you get your answer. I hope this helps.
657.1 ?
As so get the surface area you do widths X length X height and you split the diagram so you only have to work out the cube and the prism by themselves, then you add them together to get 657.135 and rounding to the nearest tenth would be 657.1 I think :))
