Answer:
121.21 people per square mile
Step-by-step explanation:
area = 1/2(12 + 21)(14) = 231 mi²
28,000/231 = 121.21 people per square mile
Area of a trapezoid formula:
A = 1/2(Base1 + Base2)*height
I will assume that WX and YZ are the two bases, since that's the only thing that logically makes sense to answer the question.
Plug in what we know
I believe the Area is meant to be 144 unit^2, as no area is ever given as 144^2
144 = 1/2(18 + 18) * h
solve for h
144 = 18 * h
h = 144/18
h = 8
The height is 8.
Step-by-step explanation:
In order to use the elimination method, you have to create variables that have the same coefficient—then you can eliminate them. Multiply the top equation by 5. Now multiply the bottom equation by −3. Next add the equations, and solve for y.
