Answer:
8 
Step-by-step explanation:
Sadly, you are doing this incorrectly.
The easiest way to find the area of this shape is to separate it into a square and a triangle.
This will leave you with a square with the dimentions 2x2 a triangle with a base of 4 and a height of 2.
The area of the square is 4 
Using the equation for the area of a triangle

We can plug in our 2 know values to get

Now we can take the sum of the areas of these two shapes to get a total area of 8 
If n is ten then the expression would change to
2(10)+4
20+4
so your answer would be 24
Answer:
The volume of the prism is the area of the base times the height. So to calculate height, divide the volume of a prism by its base area. For this example, the volume of the prism is 500 and its base area is 50. Dividing 500 by 50 results in 10.
Answer:
BC = 40º
BMC = 40º
Step-by-step explanation: Since the measure the major and minor arcs add up to 360º, just subtract 320 from 360 to find BC which is 40º. <BMC is also 40º because the measure of the arc is equal to its corresponding angle.
First, we need her speed as it will serve as the slope of the equation.
Distance = 2 km
time = 18 min
Speed = 1/9 km/min
k = (1/9)t
Where k is the distance in km and t is the time in minutes.
