5.4a+8.2=9.8a-2.8  subtract 9.8a from both sides

-4.4a+8.2=-2.8  subtract 8.2 from both sides

-4.4a=-11  divide both sides by 4.4

a=11/4.4

a=2.5
...

6(m-2)=12  perform indicated operations on left side...

6m-12=12  add 12 to both sides

6m=24 divide both sides by 6

m=4

...

6-m=5m+30  subtract 5m from both sides

6-6m=30  subtract 6 from both sides

-6m=24  divide both sides by -6

m=-4

Se desea pintar un cuadrado inscrito en una circunferencia de radio R=3cm como se muestra en la figura. Calcular el área del cua
Leno4ka [110]

Answer:

El área del cuadrado es de 3 centímetros cuadrados.

Step-by-step explanation:

Dado que se desea pintar un cuadrado inscrito en una circunferencia de radio R=3cm como se muestra en la figura, para calcular el área del cuadrado se debe realizar el siguiente cálculo:

Radio = diámetro / 2

3 = X/2

X = 6

Hipotenusa del triángulo interno: 6 cm

Aplicando teorema pitagórico: lado al cuadrado mas lado al cuadrado es igual a hipotenusa al cuadrado.

L^2 + L^2 = 6

2L^2 = 6

L^2 = 6/2

L = √ 3

L = 1.732

Área de un cuadrado = L x L = L^2 = 3

Por lo tanto, el área del cuadrado es de 3 centímetros cuadrados.
