Chelsea is budgeting for her trip to the mall. She does not want to spend any more than $140. If she wants to buy a dress that costs $28.50 and some shirts that cost $20.75 each, how many shirts can she buy? Use the inequality to help solve the problem.

- 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

40 minutes

step-by-step explanation:

add the time and multiply by 2
