Julie has a jewelry box shaped like a cube. The volume of the jewelry box is V cubic inches. Use this information to answer Questions 6 and 7. Write an expression that represents the edge length of Julie's jewelry box in inches.

  s = ∛V

Step-by-step explanation:

The relationship between edge length (s) and volume (V) of cube is ...

  V = s³

Taking the cube root of both sides of this equation gives you an expression for the edge length:

  s = ∛V

Additional comment

The units of s will be the cube root of the units of V. If V is in cubic inches, then s is in inches.

- 2 + 10x³ - 21x² + 19x - 4

step-by-step explanation:

each term in the second factor is multiplied by each term in the first factor

x²(- 2x² + 4x - 1) - 3x(- 2x² + 4x - 1) + 4(- 2x² + 4x - 1) ← distribute

= - 2 + 4x³ - x² + 6x³ - 12x² + 3x -8x² + 16x - 4

collect like terms

= - 2 + 10x³ - 21x² + 19x - 4 ← in standard form

step-by-step explanation:

the shape,the size and the distance
