(X+4)^5=3125
Use distributive property for x and 5 and 4 and 5 to get
5x+20=3125
Then subtract 20 from both sides to get
5x=3105
Then divide both sides by 5 to get
X= 621

Answer:
2x^3 + 6x^2
Step-by-step explanation:
Volumen = area * height

and the heigth is 2x
Volumen = (x^2 + 3x)* 2x
Volumen = 2x^3 + 6x^2
