The original height of the plant is 20 inches, and each week for 4 weeks its height increases by 2h inches, so at the end of 4 weeks its height would be:
20 + 4(2h) = 20 + 8h
Now for the next two weeks the plant grows in height by h inches each week, so we need to add a further 2h inches to the equation. Thus the expression that shows the height of the plant after 6 weeks is:
20 + 8h + 2h = 20 + 10h, therefor A is the correct answer
Depending on how heavy the package is, you should take the Fed Ex if the package is heavy, and the UPS for something that is small

Answer:
37.5 square units
Step-by-step explanation:
When the points are plotted on a graph, you can see that the sides of the trapezoid are the hypotenuse of a 3-4-5 right triangle (or multiple thereof). The grid lines make up the legs of the triangle, and the edge of the figure makes up the hypotenuse. Side BC is clearly twice as long as side AD.
The area formula for a trapezoid applies:
A = 1/2(b1 +b2)h
A = 1/2(5 +10)(5) = 1/2(75) = 37.5 . . . . square units area
