Question

UUUUUUUUUUURRRRGEEENNTEEE!!!!

Algueem me ajuda

Answer 1

.
$\frac{5}{x+2} = \frac{x+3}{6} \\ \\ (x+2)(x+3)=5.6 \\ x^2+5x+6-30=0 \\ x^2+5x-24=0$

Δ=5²-4(-24)
Δ=25+96
Δ=121
√Δ=√121=± 11

$x= \frac{-5\pm11}{2} \\ \\ x'= \frac{-5+11}{2} = \frac{6}{2} =3$

x" vai dar negativo , não tem medida

Logo x=3
