It is important to remember that in simplifying expressions, you can only add or subtract like terms. Also, you have to follow PEMDAS. For the expression, 

<span>5 + 7 + 15xy^2 + 9y^3 + 10x –13xy^2 – 3x – 8y^3

We can combine all the constants, xy^2 terms, y^3 terms and x terms which will yield,

12 + 2xy^2 + y^3 + 7x

Therefore the correct answer is option B.</span>

Fuaad solved an absolute value inequality and expressed the solution as . What is another way to show Fuaad’s solution? For all
Ira Lisetskai [31]

Answer:

{x I - 12 < x < 7}

Step-by-step explanation:

Fuaad solved an absolute value inequality and expressed the solution as - 12 < x < 7.

So, the value of x lies between - 12 and 7 but not including - 12 and 7.

Option C will give another way to show Fuaad's solution.

It is {x I - 12 < x < 7}, which means x is a variable which belongs with in the interval (- 12, 7). (Answer)

Answer:

124 ft2

Step-by-step explanation:

The yard is a 12ft square so the length and width would both be 12ft. You multiply the length and width of the yard to get the area of the yard so 12x12=144. You have the length and width of the flower bed so 5x4=20. Once you have the area of both you can subtract the area the flower bed takes up of the lawn. 144-20=124 ft2.

¿Cuál es el sistema de ecuaciones que permite obtener el precio por litro de los dos tipos de
vampirchik [111]

El sistema de ecuaciones que permite obtener el precio por litro de los dos tipos de gasolina es 8x + 10y = 302.12 y 12x + 12y = 400.08​ (opción D)

Una ecuación es una expresión matemática que se caracteriza por representar una igualdad entre dos miembros separados por el signo igual. La ecuaciones incluyen elementos conocidos e incógnitas relacionados mediante operaciones matemáticas.

De acuerdo a lo anterior la respuesta correcta es 8x + 10y = 302.12 y 12x + 12y = 400.08​. Por que estas ecuaciones expresan matemáticamente los datos que se tienen y las incógnitas con las letras <em>x</em> y <em>y</em>.

Por ejemplo, la primera expresa que 8 (litros) por el precio del galón de gasolina Magnum (<em>x</em>), más 10 (litros) por el precio del galón de gasolina Premium (<em>y</em>) es igual a 302.12, que fue el precio total que pagó Carlos por la gasolina.

La segunda ecuación expresa que 12 (litros) por el precio del galón de gasolina Magnum (<em>x</em>) más 12 (litros) por el precio del galón de gasolina Premium (<em>y</em>) es igual a 400.08, que fue el precio total que Raquel pagó por la gasolina.

Esta pregunta está incompleta porque faltan las opciones e información sobre la gasolina. A continuación está la información completa y las opciones.

Carlos compró 8L de gasolina Magnum y 10 litros de gasolina premium por 302.12

Raquel compró 12L de gasolina Premium y 12L de gasolina magnum por 400.08

A) 8x + 12y = 302.12

10x + 12y = 400.08

B) 8x + 12y = 400.08

10x + 12y = 302.12

C) 8x + 10y = 400.08

12x + 12y = 302.12

D) 8x + 10y = 302.12

12x + 12y = 400.08​
