Step-by-step explanation:

using 2x to multiply the second bracket I.e (2x)(3x2 +2xy+5y2)

=(6x3 +4x2y +10xy2)

using (y) to multiply the second bracket also

= (3x2y +2xy2 +5y3)

bringing the two bracket together

= 6x3 +5y3 + (10xy2 + 2xy2) +(4x2y +3x2y)

= 6x3 + 5y3 + 12xy2 + 7x2y

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
