Conveyor Design A moving conveyor is built to rise 1 meter for each 3 meters of horizontal change.
(a) Find the slope of the conveyor.
(b) Suppose the conveyor runs between two floors in a factory.
Find the length of the conveyor if the vertical distance
between floors is 10 feet.

- 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

homozygous. one is homozygous, while two is heterozygous.
