simplify 120/100=6/5
A x 6/5=54
divide both side by 6/5
A=54/(6/5)
A=54x5/6
A=45

artcher [175]

Answer:

y= $-\frac{\sqrt[3]{63} }{3}$

y=0

Step-by-step explanation:

− 4 $y^{2}$ ( 3 $y^{3}$ + 7 )

-4 $y^{2}$ =0, ( 3 $y^{3}$ + 7 )=0

$y^{2}$ =0 3 $y^{3}$ =-7

y=0 $y^{3}$ = $\frac{-7}{3}$

y= $-\frac{\sqrt[3]{63} }{3}$
