DIA [1.3K]

Answer:

Se almacena un cuaderno por caja, significando 120 cuadernos en 120 cajas iguales.

Step-by-step explanation:

A partir del enunciado, podemos calcular el número de cuadernos por caja al dividir el total de cuadernos en la carretilla por el número de cajas disponibles.

$x = \frac{120\,cuadernos}{120\,cajas}$

$x = 1\,\frac{cuadernos}{caja}$

Se almacena un cuaderno por caja, significando 120 cuadernos en 120 cajas iguales.

Natasha2012 [34]

The true statement is -2>-3

Step-by-step explanation:

The given statement included inequality and comparison symbols. The numbers involved are negative integers.

As the number increases its value decreases which means that -1 will be greater than -2 and so on

Given statement will be discussed one by one

-2 <-3

-2 comes before -3 so the statement is true as -2 will be greater than -3.

-2>-3

The statement is true because -2 is greater than -3

The true statement is -2>-3

Area of rectangle is $2x^2+x-45$

Step-by-step explanation:

Given:

Length of rectangle = 2x-9

Width of rectangle = x+5

Required:

Area of rectangle

Formula:

$Area\,\,of\,\,rectangle=Length*Width$

Putting values of length and width:

$Area\,\,of\,\,rectangle=Length*Width\\Area\,\,of\,\,rectangle=(2x-9)(x+5)\\Area\,\,of\,\,rectangle=2x(x+5)-9(x+5)\\Area\,\,of\,\,rectangle=2x^2+10x-9x-45\\Area\,\,of\,\,rectangle=2x^2+x-45$

So, Area of rectangle is $2x^2+x-45$
