podryga [215]

Answer:

x^2 +2x-3

Step-by-step explanation:

Given

(x - 2)\² + 6x - 7

Required

The equivalent

We have:

(x - 2)\² + 6x - 7

Expand

(x - 2)\² + 6x - 7 = x^2 -2x-2x +4 +6x - 7

Collect like terms

(x - 2)\² + 6x - 7 = x^2 -2x-2x+6x +4  - 7

(x - 2)\² + 6x - 7 = x^2 +2x-3

Hence, the equivalent is:

x^2 +2x-3

Alik [6]

Answer:

Dado que un obrero manufactura cajas rectangulares de distintos tamaños, y la longitud de cualquier caja debe ser superior a su ancho en al menos 3 cm, y el perímetro no puede ser superior a los 24 cm, para determinar cuáles son las medidas posibles de una caja se debe realizar el siguiente cálculo:

X + X + 6 = 24

2X = 18

X = 9

Por lo tanto, la caja puede tener 4.5 centímetros de ancho por 7.5 de largo, o bien ir aumentando su longitud en desmedro de su anchura.
