Answer: D) 32

Step-by-step explanation:

The area of a parallelogram equals its base times its height. Substitute the base and area into this formula to solve for the height:

A=bh

40=(5)(h)

h=8

If ABCD is a parallelogram, opposite sides are parallel, so AB is parallel to DC. If AB is parallel to DC, EB is parallel to DC. Since EB is parallel to DC, quadrilateral EBCD has at least one pair of parallel sides, making it a trapezoid. The area of a trapezoid is equal to \frac{h(b_{1}+b_{2})  }{2} where h is the height, b_{1} is one base, and b_{2} is the other base. Plug the necessary values into the formula:

A=\frac{h(b_{1}+b_{2})  }{2}

b_{1} =AB-AE\\DC=AB\\b_{1} =DC-AE\\b_{1} =5-2\\b_{1} =3

b_{2} =5

h=8

A=\frac{8(3+5)}{2}

A=32

The answer is D) 32.

Jake rate 6 dollers per a week or no
Liono4ka [1.6K]

Answer:

A. 6 dollars per week.

Step-by-step explanation:

Because if you look carefully in the graph, you would see that the dot on 1 week is above 5 dollars so therefore, it would be 6 dollars. To check, look at the next dot and see. You will see that the dot above 2 weeks is in the middle of 10 and 15 dollars.

Hope I helped.
