Answer:

B=9  (I'll solve right now, just so you get the answer)

Step-by-step explanation:

2x^2+14xy-36y^2=2(x+By)(x-2y)

Expand right side by distributing

(2x+2By)(x-2y)

Use the FOIL method to simplify (first, outside, inside, last):

(a+b)(c+d)=ac+ad+bc+bd

(2x*x)+(2x*(-2y))+(2By*x)+(2By*(-2y))\\\\

Simplify

2x^2-4xy+2Byx-4By^2

Re-insert

2x^2+14xy-36y^2=2x^2-4xy+2Byx-4By^2

Cancel out 2x^2

14xy-36y^2=-4xy+2Byx-4By^2

Move all terms to one side

14xy-36y^2+4xy-2Byx+4By^2=0

Simplify

18xy-36y^2-2Byx+By^2=0

Factor out the common term 2

2(9xy-18y^2-Byx+2By^2)

Agustín fabrica artículos de cuero y los vende con un incremento del 8% de su costo. Si en su última campaña utilizó un cuero de
nadezda [96]

Answer:

El aumento del precio de costo único equivalente es un aumento del 20,96% en el precio de costo

Step-by-step explanation:

Los parámetros dados son;

El porcentaje de aumento en el precio de costo que Augustin vende artículos de cuero = 8%

El aumento adicional de Augustin se aplica cuando usó cuero de mayor calidad = 12%

Sea x el precio de costo

Tenemos, el primer precio de venta = 1.08 × x

El precio de venta del cuero de alta calidad = 12% adicional al precio de venta anterior

∴ El precio de venta del cuero de alta calidad = 1,12 × 1,08 × x = 1,2096 × x

Por lo tanto, el precio de venta del cuero de alta calidad = (1.2096 × 100)% de x = 120.96% de x, lo que da;

El aumento del precio de costo único equivalente = (120,96% - 100%) aumento en x = 20,96%

∴ El aumento del precio de costo único equivalente = 20,96% de aumento en el precio de costo.
