In an earlier lesson, you saw the equation V +F - 2 = E, which relates the number of vertices, faces, and edges in a Platonic solid. Write an equation that makes it easier to find the number of vertices in an octahedron (shown here), which has 8 faces.

step-by-step explanation:

7

step-by-step explanation:

the answer would be 7

h= 12 inches

step-by-step explanation:

x coordinate can be written by using the formula, x= x1 + 2/5(x2 - x1)

step-by-step explanation:

formula

x = x1 + p/w(x2 - x1)

let the line segment ab with a(x1,y1) and b(x2,y2)

a point(x,y) divide ab in the ratio, 2: 3 the x coordinate can be written as

x = x1 + p/w(x2 - x1)

here p=2 and w = 2+3

therefore,

x coordinate can be written by using the formula, x= x1 + 2/5(x2 - x1)

similarly y coordinate y = y1 + 2/5(y2 - y1)
