Question

Solve (5 x/3) (5 x/5) =54

Answer 1

Answer:

$-\frac{9\sqrt{10} }{5}$, $\frac{9\sqrt{10} }{5}$

Step-by-step explanation:

$(5*\frac{x}{3}) * (5*\frac{x}{5} ) = 54$ calculate the product

$\frac{5x}{3} * x =54$ multiply

$\frac{5x^{2} }{3} = 54$ multiply both sides by $\frac{3}{5}$

$x^{2} =\frac{162}{5}$  separate into two solutions

x = ± $\frac{9\sqrt{10} }{5}$
