se tiene que embaldosar el patio interior de un edificio con baldosas cuadradas de 30 cm de lado. El patio es rectangular y sus
shepuryov [24]

Answer:

40,000 baldosas

Step-by-step explanation:

Lo primero que debemos hacer aquí es calcular el área del patio rectangular.

El mejor enfoque para esto es convertir primero sus medidas a centímetros

Matemáticamente, 100 cm = 1 m, entonces 10 m se convierten en 1000 cm y 12 m se convierten en 1200 m.

El área de un rectángulo es L * B y, por lo tanto, tenemos 1200 * 1000 = 1,200,000 cm ^ 2

Ahora, para saber la cantidad de azulejos que tendrá el patio, necesitaremos dividir el área del patio por el área de los azulejos

Matemáticamente, eso sería 1,200,000 / 30 = 40,000 fichas

What is the simplest form of the expression 2x(x â’ 6) â’ 7x2 â’ (13x â’ 3)? A. 5x2 â’ 25x 3 B. -5x2 â’ 25x 3 C. -5x2 x 3 D. -5x
kobusy [5.1K]

The simplest form of the given expression can be written as -5x² + 25x - 3.

The given parameters:

2x(x + 6) - 7x²  + (13x - 3)

The given expression can be simplified as follows;

2x(x + 6) - 7x² +  (13x - 3)

= 2x² + 12x -  7x² + 13x - 3

<em>collect similar terms together</em>

= (2x² - 7x²)  + (12x + 13x) - 3

= -5x² + 25x - 3

Thus, the simplest form of the given expression can be written as -5x² + 25x - 3.
