Question

Porfavor me ajudem, eu preciso de respostas ate 12:00

Answer 1

Resposta:

1) x = 1/2

2) P = 4x + 12

P = 24

Explicação passo-a-passo:

1) 3/12 + 1/4 + x = 16/16

(3 + 3)/12 + x = 1

6/12 + x = 1

1/2 + x = 1

x = 1 - 1/2

x = (2 - 1)/2

x = 1/2

2)

a) P = [(x + 1) + (x + 5) ] × 2

P = [x + 1 + x + 5] × 2

P = [2x + 6] × 2

P = 4x + 12

b) P = 4 × 3 + 12

P = 12 + 12

P = 24
