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.

I NEED HELP ASAP GIVING BRAINLIEST
Yuri [45]
If we know that 180-5=128 that means that that equation must be equal to 128.

(2^3x+1)=128

By putting 128 into exponential form with a base of 2 you get 2^7:

(2^3x+1)=2^7

Since these have the same bases we can set the exponents equal to 7. This will give us an exponent of 3x+1=7. By Subtracting across and dividing by 3 you get:

3x=6 to 3/3x = 6/2

This gives us a final answer of:

x=2
