Marianna [84]

La medida aproximada del lado faltante según el teorema de desigualdad de triángulos es:

  • más de 12 cm y menos de 48 cm

De acuerdo con el teorema de la desigualdad del triángulo que establece que;

La suma de la longitud de 2 lados cualesquiera de un triángulo debe ser mayor que el tercer lado.

Dado que :

a = 30 cm; b = 18 cm; c =?

Basado en el teorema de la desigualdad del triángulo;

  • c debe ser <(a + b)
  • c <(30 + 18); c <48 cm
  • También c> (a - b)
  • c> (30 - 18); c> 12 cm

Por lo tanto, el lado faltante debe ser menor que 48 y mayor que 12.

-3(y+3)=2y+3 <br> Please solve this question
NARA [144]

Answer:

y=-2.4y

Step-by-step explanation:

First you want to restate the problem.

-3(y+3)=2y+3

Now distribute the negative.

-3y-9=2y+3

Add 3y to both sides.

-9=5y+3

Subtract 3 from both sides.

-12=5y

And solve.

-2.4=y
