Answer: 4x3 - 24x2 + 22x -6
Step-by-step explanation:
(4x - 2)(x2 - 5x + 3)
(4x3 - 20x2 + 12x)
+ (-4x2 + 10x - 6)
4x3 - 24x2 + 22x -6
Answer: $69.75.
Step-by-step explanation:
Given: Cost of textbook before tax=$65.49
The tax on the textbook = 6.5%
∴ The tax amount = 6.5% of $65.49
⇒The tax amount = $4.26
The total cost of the textbook=Cost of textbook before tax+tax amount
=$65.49+$4.26
=$69.75
∴ The total cost of the textbook is $69.75.
5x9= 45 so there is 45 square feet
45 x 2.85= 128.25
The answer is $128.25 I believe
