Answer 1

Răspuns:

AB = 20

BC = 8

AC = AB + BC = 20 + 8 = 28

$\frac{20}{28} + \frac{28}{8} = \\ \\ = \frac{5}{7} + \frac{7}{ 2} = \\ \\ = \frac{10}{14} + \frac{49}{14} = \\ \\ = \frac{59}{14}$

Succes! ♡︎♥︎♡︎

Answer 2

AC = AB + BC = 20 + 8 = 28

AB/AC +AC/BC = 20/28 + 28/8 = 10/14  +7/2 (amplifici pe 7/2 cu 7)

10/14 + 49/14  = 59/14 = 59/14 = 4,21
