Kelly works at her own nail salon. Today, she did 9 manicures and received $47.25 overall in tips. If x represents the cost of each manicure, which of the following equations can be used to find the total amount of money she earned,
including tips, for her nail salon today?
A y = 9x + 47.25
B. y = 47.25(x +9)
c. y = 47.25x + 9
D
y = 9(x + 47.25)

- 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

no ,sorry if you needed it but you can ask and try to see if any one will anwser ,
