Alessandro, a graduate student at a local college, is picking a suit to where to his job interview. He has to decide among the following options: either the blue or white or red shirt, either the blue or black pants, and a tie that is either striped or solid. How many different suit combinations does Alessandro have to choose from

- 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

the answer would be 484

step-by-step explanation:

just multiply 0.484 times 1,000 (formula)
