if xy=10, what is the value of 2 times x/y times y^2? Please explain your answers.

a) 5
b)8
c)10
d)12
e)20


Sagot :

e) 20... x/y * y^2 = xy. 2xy = 2*10 = 20
x = 10/y,

so[tex] 2 \times x/y \times y^2[/tex]

= [tex]2 \times \frac{10/y}{y} \times y^2 [/tex]

= [tex]= 2\times 10y^2/y^2[/tex]

=[tex]=2\times 10 =20[/tex]
