Answer:
(2x² + 3y)(4
- 6x²y + 9y²)
Step-by-step explanation:
A sum of cubes is factored in general as
a³ + b³ = (a + b)(a² - ab + b²) , thus
8
+ 27y³
= (2x²)³ + (3y)³ with a = 2x² and b = 3y
= (2x² + 3y)((2x²)² - 2x²(3y) + (3y)²)
= (2x² + 3y)(4
- 6x²y + 9y²)
Answer:
188 meters cubed
Step-by-step explanation:
- radius = 1/2d d=6 radius =3 height 20
- formula for thia equation is 1/3 (3.14)(3^2)(20)
- (3.14)(9)(20)
- 3.14 x 9 = 28.26
- 28.26 x 20 = 565.2
- 565.2/3 = 188.40
- 188.4 round to 3sf is 188
