The volume is scale factor³
Take the square root of the volume ratio

which is


The ratio of their radii is 3 : 5
▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬
(Ⅰ) 2v² - 2v³ - 7 + 7v :
Standard Form → 2v³ + 2v² + 7v - 7v
Number of terms → Four (Polynomial)
Degree of Polynomial → Highest degree 3 (Cubic)
(Ⅱ) -3m -8m -7m²
Standard Form → -7m² - 8m - 3m
Number of terms → Three (Trinomial)
Degre of Polynomial → Highest degree 2 (Quadratic)
