<u>Answer:</u>

The factorization of given expression x^2 + 81 is (x + 9i)(x – 9i) and option d is correct.

<u>Solution:</u>

Given, expression is x^2 + 81

We have to factor it in the complex numbers.

Let us check options to find answer.

<em><u>A) (x – 9)(x – 9)  </u></em>

(x – 9)( x – 9)  =(x-9)^{2}=x^{2}-18 x+81

So, this is not correct answer.

<u><em>B) (x + 9)(x + 9)  </em></u>

(x+9)(x+9)=(x+9)^{2}=x^{2}+18 x+81

So, this is not correct answer.

<u><em>C) (x + 9i)(x + 9i) </em></u>

(x+9 i)(x+9 i)=(x+9 i)^{2}=x^{2}+18 x i+81(-1)=x^{2}+18 x i-81

So, this is not correct answer.

<u><em>D) (x + 9i)(x - 9i) </em></u>

(x+9 i)(x-9 i)=x^{2}-(9 i)^{2}=x^{2}-(-81)=x^{2}+81

Thus option D is correct

Hence, the factorization of given expression is (x + 9i)(x – 9i). and option d is correct.

En la figura los segmentos ED y AC son paralelos selecciona los triangulos q son 1)Triangulo ABE 2)Triangulo BCD 3) Triangulo BD
Flauer [41]

Respuesta:

Los 3 triángulos son semejantes.

Explicación paso a paso:

En estos casos nos dan a conocer los ángulos de los triángulos, por lo tanto el criterios de semejanza se reduce si más de dos de sus ángulos internos son iguales.  

Por lo tanto, sabemos que en los triángulos ABE y BCD presentan los mismos ángulos, 80°, 40° y 60° por lo que podemos afirmar que ambos triángulos son semejantes.

Ahora bien, para el triangulo BDE, podemos conocer solo un angulo del que es de 80°, pero el resto sería desconocido, lo que quiere decir que no podríamos determinar si es semejante con los otros, pero por medio de los ángulos externos determinamos que si corresponde también a 60° y 40°, por lo tanto, los 3 triángulos son semejantes.

If N is a 3-digit integer, and the result of reversing the digits of N is the number M, what is the maximum value of N-M? Please
Lena [83]

Answer:

The maximum value of N-M will be 792

Step-by-step explanation:

For N - M to be maximum

N must be very large and M must be very small

largest 3 numbers occur in 900's and smallest 3 digit numbers occur in 100's

so we need such an N which starts with 9 and ends with 1 so that on reversing it produces a number starting with 1.

If N = 901 , M will be 109

N - M = 792

This is the largest possible value of N - M

All other values of N-M will give a smaller value than 792.
