Answer:

7cm

Step-by-step explanation:

One side of a square is increased by 8 cm, let us say the length got increased by 8 cm. So we have length of x + 8 cm

An adjacent side, the width, decreased by 2 cm. So we have width of x - 2cm

Perimeter of rectangle = 2(length + width)

40 = 2( (x + 8) + ( x - 2) )

40 = 2( 2x + 6)

40 = 4x + 12

28 = 4x

x = 7 cm

That is 7 cm of the length of the side of the square

El area del cuadrado mide 25 pies cuadrados cuál es la longitud de un lado del cuadrado?
Anna [14]
Sabiendo que el área del cuadrado cuyos lados miden (cada uno) "a" es igual a "a²" (A=a²), simplemente sustituimos el área por 625 m² y resolvemos la ecuación: 

<span>a² = 625 m² --> a = √(625 m²) --> a = 25m </span>

<span>Solución: Cada lado mide 25 metros. </span>


<span>Explicación de por qué el área del cuadrado con lados de longitud "a" es "a²": </span>
<span>El área de cualquier cuadrilátero es igual a la base por la altura de éste. Siendo en el cuadrado todos los lados iguales, la base y la altura también son iguales. Por lo tanto, el área del cuadrado sera el siguiente: </span>
<span>Área = Base x Altura = a x a = a² </span>

Solve the inequality 2x-7&gt;3
Licemer1 [7]

Answer:

x>5

Step-by-step explanation:

2x - 7 > 3

Add 7 to both sides

2x - 7 +7 > 3+7

2x > 10

Divide both sides by 2

2x/2 > 10/2

x > 5
