Answer: x=4

Step-by-step explanation:

We know that line segment AC= AB + BC

we also know that AB= 3x+8 and BC= 2x-5

by substituting these, we get AC= (3x+8)+(2x-5)

AC is given as being 23, so we know that

23= (3x+8)+(2x-5)

by combining like terms, we get that

5x+3=23

simplify this to get that x=4

Find the difference when the polynomial -5x^2+3x+8 is subtracted from the polynomial 2x^2+4x+1.
geniusboy [140]

The difference is 7x^{2}  + 1x-7.

Step-by-step explanation:

Step 1:

The polynomial -5x^{2}+3x+8 is subtracted from the polynomial 2x^{2} + 4x +1.

If we write this as an equation, we get

(2x^{2} + 4x +1) -(-5x^{2}+3x+8).

To subtract the polynomials, we group up the terms based on their variables.

In this subtraction, there are two variables i.e. x^{2} and x and there is one constant term.

Step 2:

The subtraction of the x^{2} variables; 2x^{2}  -(-5x^{2} )  = 2x^{2} +5x^{2} = 7x^{2}.

The subtraction of the x variables; 4x - (3x) = 1x.

The subtraction of the constants; 1-(8) = -7.

So (2x^{2} + 4x +1) -(-5x^{2}+3x+8) = 7x^{2}  + 1x-7.

Elaborar un informe acerca de las formas de calcular las necesidades y los costos para construir un sistema de riego.
Savatey [412]

Step-by-step explanation:

Algunos aspectos importantes que debes incluir en tu informe son los siguientes:

Para saber cual es el sistema de riego mas adecuado debemos hacer un análisis primero de las necesidades y requerimientos del cultivo o vegetación ,asi como saber con exactitud cuales son las dimensiones del terreno y las condiciones del clima del lugar.

Lo anterior nos ayudara a elegir  un sistema de riego adecuado que nos permita suplir las necesidades de nuestro cultivo y a la vez reducir costos .

De los métodos de riego que existen ,los sistemas  automatizados e informatizados surgen como una gran alternativa para controlar el uso del agua a la vez que permite disminuir costos por el gran ahorro que representa, así mismo este tipo de riego permite una mejor distribución del recurso hídrico por toda el área.

Por lo general estos sistemas de riego están centralizados en un único punto de control lo que facilita su mantenimiento así como la prevención de futuras anomalías que se pudieran presentar.
