Step-by-step explanation:

$= \frac{ \frac{3}{x - 2} - 5 }{2 - \frac{4}{x - 2} }$

$= \frac{ \frac{3 - 5.(x - 2)}{x - 2} }{ \frac{2.(x - 2) - 4}{x - 2} }$

$= \frac{ \frac{3 - 5.(x - 2)}{ \cancel{x - 2}} }{ \frac{2.(x - 2) - 4}{ \cancel{x - 2} }}$

$= \frac{3 - 5.(x - 2)}{2.(x - 2) - 4}$

$= \frac{3 - 5x + 10}{2x - 4 - 4}$

$= \frac{ - 5x + 13}{2x - 8}$

$= \frac{13 - 5x}{2x - 8}$

The answer is D.

A polyhedron has 8 vertices and 14 edges. How many faces must it have?

Scorpion4ik [409]

We know that

The Euler's formula state that, the number of vertices, minus the number of edges, plus the number of faces, is equal to two

V - E + F = 2
clear F
F=2-V+E

in this problem
V=8
E=14
F=?
so
F=2-8+14
F=8

the answer is
8 faces

Help! Best answer gets brainliest

julsineya [31]

Answer:

7.9

Step-by-step explanation:

the first thing to do is find the second projection.

16-7 = 9

than we can use a proportion to find BD

7 : BD = BD : 9

BD = √9 x 7 = √63 = 7.9

we have to use the square root because in the proportion BD Is repeated two times. If we don’t use it, we find BD^2
