A quadratic equation is an equation whose leading coefficient is of the second degree. The given quadratic equation can be matched with its solution as shown below.

<h3>What is a quadratic equation?</h3>

A quadratic equation is an equation whose leading coefficient is of second degree also the equation has only one unknown while it has 3 unknown numbers. It is written in the form of ax²+bx+c.

The given quadratic equation can be matched with its solution as shown below,

2x² − 32 = 0 → x = √(32/2) → x = {-4, 4}

4x² − 100 = 0 → x = √(100/4) → x = {-5,5}

x² − 55 = 9 → x = √(9+55) → x = {-8,8}

x² − 140 = -19 → x = √(-19+140) → x = {-11,11}

2x² − 18 = 0 → x = √(18/2) → x = {-3, 3}

los miembros de un club social se pueden agrupar en sin que ninguno quede suelto, por parejas, por trios y por grupos de 7. ¿ cu
mote1985 [20]

Answer:

El club tiene 84 miembros.

Step-by-step explanation:

El mínimo común múltiplo (mcm) es el número positivo más pequeño que es múltiplo de dos o más números. Es decir, el mínimo común múltiplo de dos números a y b es el número más pequeño que es múltiplo de a y múltiplo de b. Recordar que los múltiplos son el resultado de multiplicar un número por todos y cada uno de los números naturales.

Para calcular el mcm se descompone los números para escribirlos como un producto de números primos. Para descomponer un número se divide el número sucesivamente entre números primos hasta llegar a 1.  La descomposición es el producto de las potencias de los números primos, siendo sus exponentes el número de veces que se ha dividido por dicho primo.

El mínimo común múltiplo se obtiene escogiendo todos los factores (comunes y no comunes), elevados a la máxima potencia. Es decir eliges todos los factores, pero los que se repitan serán elevados a la máxima potencia.

En este caso, los miembros de un club social se pueden agrupar, sin que ninguno quede suelto, por parejas, por tríos y por grupos de 7. Para calcular la cantidad de miembros que tiene el club, entonces debes calcular el mcm entre los números 2,3 y 7

No podemos descomponer los números como producto de primos porque ya son números primos., por lo que el mínimo común múltiplo es el producto de comunes y no comunes al mayor exponente:

mcm (2,3,7)= 2*3*7= 42

Pero sabes que los miembros son más de 80 pero menos de 90, por lo que calculas un múltiplo del mcm obtenido.

Múltiplo de 42= 2*42= 84

<u><em>El club tiene 84 miembros.</em></u>

Let ​ x^2+18x=44 .​ What values make an equivalent number sentence after completing the square?
Lostsunrise [7]
To find the final term to compete the square you need to divide the 'x' term by 2 then square it

x^2 +18x + = 44+ \\ x^2+18x+( \frac{18}{2} )^2=44+( \frac{18}{2} )^2 \\ x^2+18x+9^2=44+9^2 \\ x^2+18x+81=44+81 \\ (x+9)^2=125 - equivalent equation

xenn [34]

Answer:

d+8

Step-by-step explanation:

Let d represent number of dolls in 2nd basket.

We have been given that a day-care center has 2 baskets of dolls. One basket has 8 dolls, and the other basket has an unknown number of dolls in it. We are asked to represent this situation in an expression.

The number in both baskets would be equal to dolls in 1st basket plus dolls in 2nd basket.

We can represent this information in an expression as:

d+8

Therefore, our required expression would be d+8, where d represents number of dolls in 2nd basket.
