Question

Me ajudem por favor:​

Answer 1

Resposta:

C) x = 7

D) x = 5

Explicação passo-a-passo:

Teorema de Tales

C)

(x + 2)/3 = (2x + 1)/5

5.(x + 2) = 3.(2x + 1)

5x + 10 = 6x + 3

6x - 5x = 10 - 3

x = 7

D)

(3x + 1)/4 = (5x - 1)/6

6.(3x + 1) = 4.(5x - 1)

18x + 6 = 20x - 4

20x - 18x = 6 + 4

2x = 10

x = 10/2 = 5
