Question

Me ajudam há resolver esse quadro

Answer 1

a

x = 5

x + 1 = 5 + 1 = 6 ***resposta

2x + 4 = 2(5) + 4 = 10 + 4 = 14 **** resposta

x² + 1 = ( 5)² + 1 = 25 + 1 = 26 **** resposta

b

x = 10

x + 1 = 10 + 1 = 11 ***

2x + 4 = 2 (10 ) + 4 = 20 + 4 = 24 ****

x² + 1 = (10)² + 1 = 100 + 1 = 101 ****

c

x = 2,5

x + 1 = 2,5 + 1,0 = 3,5 ****

2x + 4 = 2 ( 2,5) + 4 = 5 + 4 = 9 ****

x² + 1 = ( 2,5)² + 1 = 6,25 + 1,00 = 7,25 ***

d

x = 0,3

x + 1 = 0,3 + 1,0 = 1,3 ***

2x + 4 = 2 ( 0,3) + 4 = 0,6 + 4,0 = 4,6 ***

x² + 1 = ( 0,3)² + 1 = 0,09 + 1,00 = 1,09 ***
