Question

Un rectangulo tiene un largo de x + 5 y ancho de x – 3. Cual es el area del rectangulo?

Escriba la respuesta como un pilonomio en forma estandar.

Answer 1

Area=
`x^2+2x-15`

Explanation:

-Area of a rectangle is given as the product of it's length and width.

`A=lw`

-Given the length is (x+5) and the width is (x-3), the area is calculated as follows:

`A=lw\\\\=(x+5)(x-3)\\\\=x^2-3x+5x-15\\\\=x^2+2x-15`

Hence, the area of the rectangle as a standard polynomial is given as
`x^2+2x-15`
