Which of the following formulas could be used to determine the surface area of a cylinder sandwiched between one
cone and half of a sphere?
SA = 21w + 21h + 2wh
SA= 2B + Ph
SA = 212 + 12
SA = 277 th + 272
SA=TA + 2

- 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
