A van is 5 meters long in real life. A scale drawing uses the scale of 4 cm: 1 meter. How
long should the van be on the scale drawing?

20cm

Step-by-step explanation:

4cm=1m

van=5m

4x5=20cm

- 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

i understand 100% 10/10 hit or miss?
