We have the following expression given:

(4y^3+28y^2)+(y+7)

We can start selecting as common factor 4y^2 and we got:

4y^2(y+7)+(y+7)

Now we can select y+7 as common factor and we got:

(y+7)\left\lbrack 4y^2+1\right\rbrack

So then our final answer would be:

(y+7)(4y^2+1)

-3y+1/3=-5/6y-5/2 what does y equal
kotykmax [81]

Answer:

17/13

Step-by-step explanation:

- 3y +  \frac{1}{3}  =  -  \frac{5}{6}y -  \frac{5}{2}  \\  -  \frac{18}{6}y  +  \frac{2}{6}  =  -  \frac{5}{6} y -  \frac{15}{6}  \\   \frac{2}{6}  +  \frac{15}{6}  =  -  \frac{5}{6} y +  \frac{18}{6} y \\  \frac{17}{6}  =  \frac{13}{6} y \\  \frac{6}{13}  \times  \frac{17}{6}  = y \\  \frac{17}{13}  = y
