Answer:
Cost to buy and run the first car for 5 years=$24000
Cost to buy and run the second car for 5 years=$26000
I think we should buy the first car, because It is cheaper to buy and maintain
Step-by-step explanation:
first car:
Cost $18000 to buy
Cost $100 to maintain each month
5years =5 x 12=60months
Cost to maintain for 60months=100x60=$6000
First car cost to buy and run over the 5 year period=18000+6000=$24000
Second car:
It cost $22400 to buy
Cost $60 to maintain each month
5years=60months
Cost to maintain for 60months is 60 x 60=$3600
Cost to buy and run over the second car for 5years is 22400+3600=$26000

Answer:
3 x^2 +12x-9
Step-by-step explanation:
5x^2 - (2x-3)^2
We need to FOIL the second term
(2x-3)^2 = (2x-3) (2x-3) = 4x^2 -6x-6x+9 = 4x^2 -12x+9
Replacing it in to the original equation
5x^2 - (4x^2 -12x+9)
Distribute the minus sign
5x^2 - 4x^2 +12x-9
Combine like terms
x^2 +12x-9
