Figure out and understand how exactly you learn and process things and information then simply take it from there.

Read the books given to you and Bing/Google search things of your questioning. Read over the things you will be tested on, Get some nice study music on (something you enjoy nothing to genetic), read your books, quiz yourself to make sure you understand and take these ideas and create your own solutions through figuring out how you'd like to get ready.

1) Calcula la diagonales de un poligono n lados. Heptágono: 2 puntos

ahrayia [7]

Answer:

El número de diagonales de un polígono de n lados se calcula mediante la siguiente fórmula:

$d = \frac{n\cdot (n-3)}{2}$ (1)

Donde:

$d$ - Cantidad de diagonales del polígono.

$n$ - Cantidad de lados del polígono.

Bajo esta fórmula, tenemos los siguientes resultados:

a) El heptágono tiene 14 diagonales.

b) El octágono tiene 20 diagonales.

c) El eneágono tiene 27 diagonales.

d) El decágono tiene 35 diagonales.

e) El pentadecágono tiene 90 diagonales.

Explanation:

La cantidad de diagonales de un polígono se puede determinar mediante la siguiente ecuación:

$d = \frac{n\cdot (n-3)}{2}$ (1)

Donde:

$d$ - Cantidad de diagonales del polígono.

$n$ - Cantidad de lados del polígono.

A continuación, calculamos la cantidad de diagonales de los siguientes polígonos:

Heptágono ( $n = 7$ )

$d = \frac{7\cdot (7-3)}{2}$

$d = 14$

El heptágono tiene 14 diagonales.

Octágono ( $n = 8$ )

$d = \frac{8\cdot (8-3)}{2}$

$d = 20$

El octágono tiene 20 diagonales.

Eneágono ( $n = 9$ )

$d = \frac{9\cdot (9-3)}{2}$

$d = 27$

El eneágono tiene 27 diagonales.

Decágono ( $n = 10$ )

$d = \frac{10\cdot (10-3)}{2}$

$d = 35$

El decágono tiene 35 diagonales.

Pentadecágono ( $n = 15$ )

$d = \frac{15\cdot (15-3)}{2}$

$d = 90$

El pentadecágono tiene 90 diagonales.

Given the equation 5+x-14=x-7: Part A. Solve the equation 5+x-14=x-7. In your final answer, be sure to state the solution and in

docker41 [41]

Part 1/

5 + x - 14 = x - 7
We’ll cancel (X) from both sides;
5 - 14 = -7
-9 = -7
Since, -9 = -7 is False, there is no solution.

———

Part2/

If we use x = -2, 0, 3

1) Case of X = -2

5 + (-2) - 14 = (-2) - 7
5 - 2 - 14 = -2 - 7
3 - 14 = -9
-11 = -9 .... False / No Solution

2) Case of X = 0

5 + (0) - 14 = (0) - 7
5 - 14 = -7
-9 = -7 ... False / No Solution

3) Case of X = 3
5 + (3) - 14 = (3) - 7
8 - 14 = -4
-6 = -4 ... False / No Solution
