Sergio [31]

Answer:

<h3>5</h3>

Step-by-step explanation:

Given the expression

2a^3−10ab^2+3a^3−ab^2−7

We are to find the coefficient of a^3

First is to collect the like terms;

2a^3−10ab^2+3a^3−ab^2−7

= 2a^3+3a^3−10ab^2−ab^2−7

= 5a^3-11ab^2-7

From the resulting equation, you can see that the coefficient of the term having a^3 is 5

Un rectangulo tiene area de 15/40 cm cuadrados y sabemos que uno de sus lados mide 5/8 cuanto medira el otro lado
GaryK [48]

Queremos encontrar la medida de un lado de un rectangulo, dado que conocemos la longitud del otro lado y el area del rectangulo.

Veremos que el otro lado del rectangulo mide 3/5 cm

Sabemos que para un rectangulo de largo L y ancho W, el area esta dada por:

A = L*W

En este caso sabemos que el area es igual a (15/40) cm^2.

Y sabemos que uno de sus lados (digamos que es el ancho) mide (5/8) cm.

Entonces podemos reemplazar eso en la ecuación del area:

(15/40) cm^2 = L*(5/8) cm.

Ahora podemos resolver esto para L.

L = (15/40 cm^2)/(5/8 cm) = (15/40 cm^2)*(8/5 cm^-1)

L = 3/5 cm

El otro lado del rectangulo mide 3/5 cm
