4. Alex needs to rent a minivan for a week to take his band on tour. Easyvans charges $230 plus $0.10/km. Cars for All Seasons charges
$150 plus $0.22/km.
a) Write an equation for each rental company.
b) Graph your equations.
c) Which rental company would you recommend to Alex? Explain

- 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

unless if u could do my questions, if not i wouldn't want to
