Drawing : Actual

Scale

           2 : 10

     2 cm : 10 feet

Length

    6 cm : 30 feet

Width

    4 cm : 20 feet

The actual dimensions of the room are - Length=30 feet, Width=20 feet.

The answer is the second one.

Step-by-step explanation:

- 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
