First let's write it down, 

 x + (2x - 3) + (3x - 5) 

Then remove the parentheses

 x + 2x - 3 + 3x - 5 

 first combine the x + 2x = 3x to obtain: 3x - 3 + 3x - 5 

 then combine the 3x + 3x = 6x to obtain: 

 6x - 3 - 5 

rewrite 6x - 3 - 5 as 6x + (-3) + (-5) 

And the answer would be 6x + (-8) = 

<u>6x - 8</u>

I hope my answer helped you

se quiere pintar una pared en forma de hexágono regular y se sabe que cada lado mide 3m y que su apotema es de 2,8m cual es el a
qwelly [4]

Answer:

El área total a pintar será:

A_{tot}=25.2\: m^{2}

Step-by-step explanation:

Sabiendo el apotema y la longitu de los lados, podemos encontrar el área de un triangulo. Recordemos que, si trazamos rectas del centro del hexágono a los vértices, se formaran 6 triángulos equiláteros.

El área de un triángulo es:

A_{t1}=\frac{b*a}{2}

b es la longitud de la base (b=3 m)

a es la apotema, osea la altura del triangulo (a = 2.8)

A_{t1}=\frac{2.8*3}{2}

A_{t1}=4.2\: m^{2}

Ahora, solo debemos mutiplicar ese valor por 6 para determianr el área total de la pared.

A_{tot}=25.2\: m^{2}

Espero te haya sido util!

Please help me with this Ixl answer.Please answer this correctly I have to show them the
frosja888 [35]

Hello!

Let's put this as a system of equations.

r= 8+g

r+g=14

Let's plug our r value into the second equation and solve for g.

8+g+g=14

8+2g=14

Now we subtract 8 from both sides.

2g=6

We divide both sides by 2.

g=3

Therefore, he has 3 green peppers.

I hope this helps!

The perpendicular slope is -4/3

Step-by-step explanation:

Perpendicular slopes multiply to -1

m * 3/4 = -1

Multiply each side by 4/3

m * 3/4 *4/3 = -1 * 4/3

m = -4/3

The perpendicular slope is -4/3
