First, we multiply the given expressions:
(a + 3b) (-a² + 4ab + 2b)
= -a³ + 4a²b + 2ab - 3a²b + 12ab² + 6b²
Simplifying:

-a³ + a²b + 2ab + 12ab² + 6b²

By comparison, we can determine the values of x and y, which work out to be:
x = 1
b = 6

Answer:

1. 34.42 Toneladas

2. 28.640 toneladas

3. 38 toneladas

4.\frac{15}{10} o 1\frac{5}{10}

5.\frac{16}{6} o 2\frac{4}{6}

6.\frac{8}{4} o 2

1.1 Solucioné el problema convirtiendo el .25 en fracción.

2.1 Conviertes el denominador en el mismo buscando el minimo comun multiplo

3.1 0.099

\frac{1}{4}

\frac{1}{3}

\frac{2}{3}

0.7

0.75

1.1

\frac{3}{2}

Step-by-step explanation:

Acuerdate que para solucionar las fracciones mixtas solo tienes que dividir el denominador al nominador, por ejemplo en si tienes \frac{10}{3} entonces el 3 cabe 3 veces en el 10, y sobra 1, entonces quedamos que en mixta la fracción sería 3\frac{1}{3}

Entonces una vez que recordamos eso, podemos resolver los problemas de fracciones sin ningún problema vamos a resolver la número 4:

\frac{8}{10} +\frac{7}{10}

Como el denominador es igual, sólo sumamos el nominador:

\frac{8+7}{10}

\frac{15}{10}

Cómo el 10 cabe 1 vez en el 15, tenemos un entero y sobran 5:

1\frac{5}{10}

9(x+3)=3(3x+6)+9 how many solutions?
Slav-nsk [51]

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

9(x +3) = 3(3x + 6) + 9

9x + 27 = 9x + 18 + 9

9x + 27 = 9x + 27

The two sides of this equation are exactly the same, so the above equation holds for any value of x , <em>thus we have infinite solution for it.</em>

A) 6x + 4x -6 = 24 + 9x

    10x - 6 = 24 + 9x

    10x - 9x = 24 + 6

    X=30
