Answer:

0.897

Step-by-step explanation:

Brahmagupta formula for quadratic equation ax^2+bx=c is

x=\dfrac{\sqrt{4ac+b^2}-b}{2a}

It involved only one solution.

The given equation is

3x^2+4x=6

Here, a=3, b=4 and c=6. Put these values in the above formula.

x=\dfrac{\sqrt{4(3)(6)+(4)^2}-4}{2(3)}

x=\dfrac{\sqrt{4(3)(6)+(4)^2}-4}{2(3)}

x=\dfrac{\sqrt{72+16}-4}{6}

x=\dfrac{\sqrt{88}-4}{6}

x\approx \dfrac{5.38}{6}

x\approx 0.897

Therefore, the required solution is 0.897.

tres hermanos danvueltas circuito en bicicleta. el mayor tarda 18 en dar Una vuelta el del medio 24 minutos yel menos 36 minutos
hodyreva [135]
Tienes que hallar el mínimo común múltiplo de las 3 cantidades.

18= 2×3²
24= 2³×3
36= 2²×3²

mcm(18,24,36) = 2³×3²=8×9= 72

Eso quier decir que si partieron a la misma hora se encontraran  de nuevo en el punto de partida 72 minutos después de la salida.

Las vueltas que habrán realizado será el resultado de dividir 72 entre el tiempo que tardan en dar una vuelta

<span>Mayor: </span>  = 4

<span>Mediano: </span>  = 3

<span>Pequeño: </span>  =  2

Soluciónes:

se vuelven a encontrar a los 72 min de la salida
<span>El mayor dió 4 vueltas, el mediano 3 y el pequeño 2</span>

There would be 60 questions on the test.

90%=54
1%= 54/90 = 6/10
100%= 6×100/10 =6×10=60

3.Escribe un polinomio que cumpla con las condiciones dadas
Free_Kalibri [48]

Answer: 4x^6

Step-by-step explanation:

Para responder esta pregunta debemos conocer que es un monomio, su grado y el coeficiente.

Un monomio es un polinomio que posee 1 solo termino, el grado se refiera a la potencia a la que esta elevada la variable (en este caso usaremos la letra x)

El coeficiente es el número que está a la izquierda de una variable:

Entonces:

Monomio de grado 6 y coeficiente 4

4x^6

If someone could work out the first half of the problem and explain that would be great!
andrew-mc [135]

Answer:

x = -5

y = -5

Step-by-step explanation:

If you multiply the top equation by negative 2, you can add it to the bottom equation and cancel out the x:

-2(-x + 5y = -20) --> 2x - 10y = 40

Add this to the bottom equation top to bottom:

2x - 10y = 40

-2x + 4y = -10

You get:

-6y = 30

Then solve for y:

y = -5

Plug this back in for either equation and solve for x:

-x + 5(-5) = -20

-x -25 = -20

-x = 5

x = -5

Your answers are:

x = -5

y = -5
