Question

en la ecuación que se da a continuación despeja la incógnita "a"​

Answer 1

Respuesta:

$\frac{ \sqrt{ab + ac} }{3d} = 2 + d$

$({\frac{ \sqrt{ab + ac} }{3d}) }^{2} = {(2 + d)}^{2}$

$\frac{ab + ac}{9 {d}^{2} } = {(2 + d)}^{2}$

$a(b + c) = {(2 + d)}^{2} (9 {d}^{2} )$

$a = \frac{9 {d}^{2} {(2 + d)}^{2} }{b + c}$
