Question

ajudem teoremas de Pitágoras por favorrrrrrrrrrr

Answer 1

Resposta:

Explicação passo a passo:

$\frac{x+2}{2x+1} =\frac{3}{5}$

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

$6x+3=5x+10$

$6x-5x=10-3$

$x=7$

$\frac{4x+1}{x+2} =\frac{16}{18}$

$\frac{4x+1}{x+2} =\frac{8}{9}$

$9.(4x+1)=8.(x+2)$

$36x+9=8x+16$

$36x-8x=16-9$

  $28x=7$

    $x=\frac{7}{28}$

    $x=\frac{1}{4}$
