9×27+2×31-28= n
243+62-28=n
277=n
n=277
(2,88)
(6,64)
(9,46)
(15,10)
first find y=mx+b
88=-6(2)+b
b=100
y=-6x+100
then plug for y and solve for x or vise versa.

Step-by-step explanation:
The area of a regular octahedron is given by:
area =
. Let a is the length of the edge (diagonal).
area = 
Given that the diagonal of the octahedron is equal to height (h) of the tetrahedron i.e.
a = h, where h is the height of the tetrahedron and a is the diagonal of the octahedron. Let the edge of the tetrrahedron be e. To find the edge of the tetrahedron, we use:

The area of a tetrahedron is given by:
area =
=
The ratio of area of regular octahedron to area tetrahedron regular is given as:
Ratio =
