KIM [24]

Answer:

Paso 1:

Encuentra el área del patio trasero

Dado eso, el patio trasero mide 24 por 30 metros.

Área = largo x ancho

Área = 24 x 30 = 720

Por lo tanto, el área del patio trasero es de 720 metros cuadrados.

Paso 2:

Dado que el área de césped = 368 metros cuadrados

Luego, área de jardín = área de patio trasero - área de césped

área del jardín = 720 - 368

área de jardín = 352 metros cuadrados

Paso 3:

Encuentra las dimensiones del jardín

Sea "x" el ancho de la franja de césped

Entonces, las dimensiones del jardín son:

Longitud del jardín = 24 - 2x

Ancho del jardín = 30 - 2x

Luego,

área del jardín = (24 - 2x) (30 - 2x)



Factoriza el lado izquierdo

(x - 23) (x - 4) = 0

Por propiedad de factor cero,

x = 23 o x = 4

La solución x = 23 hace que las dimensiones del jardín sean negativas, por lo que la rechazamos

Ivahew [28]

Step-by-step explanation:

b.3n/2 = 7/2

6n = 14

n = 2 1/3

c.-x/2 + 6 = -13/4

-x/2 = -37/4

-4x = -74

x = 18 1/2

d.3x/10 = 2/5

15x = 20

x = 1 1/3

e.x/10 = -20/3

3x = -200

x = -66 2/3

f.269x/56 = 10

269x = 560

x = 2 22/269
