Answer:

Step-by-step explanation:
Please see the attached picture for the full solution.
☆ 
Put the coordinates of the point in for x, y, and z and see what the new constant is.
Your plane is
5x +4y +2z = -31
C. polygons!!
the polygons it is made of are called faces. the edges of the faces are called the edges of the polyhedron
We let
x as the bushels of apples used to make apple cider
y as the bushels of apples used to make apple juice
The system of equations is
x + y = 18
20x + 15y = 330
Solving for x and y
x = 12
y = 6
12 bushels of apples are needed to produce apple cider
6 bushels of apples are needed to produce apple juice<span />
Answer:
If all three of the latitudes lie entirely outside the triangle
its a because all the altitudes have to cross each other so when an obtuse angle is being measured the altitudes have to cross but the only way they can can cross is if they are outside of the angle to get the right mesaurement.
so yes its possible.
