Valor numérico de expresiones
Calcula el valor de cada expresión para el valor de x dado.
x² + 4= (x = 3)
6x − 8= (x = 8)
x² + 20= (x = 6)
9x − 18= (x = 2)
8x + 3= (x = 5)
2(x + 4)= (x = 8)
x² + 2= (x = 9)
5x − 18= (x = 8)
5x − 19= (x = 4)
5x − 11= (x = 3)
4(x + 1)= (x = 7)
4(x + 8)= (x = 4)
6(x + 9)= (x = 4)
5(x + 5)= (x = 2)
5x + 8= (x = 5)
4x + 5= (x = 6)
3(x + 3)= (x = 3)
7(x + 5)= (x = 10)
