Answer 1

Alternativa " A "

$2( \frac{ 2x}{3} + 5) + \frac{x - 6}{2} = 29$

$\frac{4x}{3} + 10 + \frac{x - 6}{2} = 29$

$\frac{8x + 60 + 3x - 18}{6} = 29$

$11x + 42 = 174$

$11x = 132$

$x = \frac{132}{11}$

$\boxed{x = 11}$

Alternativa " B "

• 2 lados congruentes

$\frac{2x}{3} + 5$

$\frac{2(11)}{3} + 5$

$\frac{22}{3} + 5$

$\frac{22 + 15}{3}$

$\boxed{ \frac{37}{3} }$

• Lado

$\frac{x - 6}{2}$

$\frac{11 - 6}{2}$

$\boxed{ \frac{5}{2} }$

Answer 2

Resposta:

x= 11 cm

Explicação passo-a-passo:

$\frac{2x}{3} + 5 + \frac{2x}{3} + 5 + \frac{x - 6}{2} = 29$

m.m.c=6

4x+30+4x+30+3x-18=174

11x+60-18=174

11x+42=174

11x=174-42

11x=132

x=132/11

x=11cm
