Are there any numbers of how many there are of the different colors?
Firstly you have to multiply the brackets
(c+8)(c-8)
3(2y+5)(2y-5)
There are no like terms so it's still ab^2-b
Answer:
18
Step-by-step explanation:
180X10=1800
1800/100=18
Round trip travel: 2*15miles*$0.45/mile = $13.5
Equipment: $84 + $15.50 + $47 + $32 + $22 = $200.50
Tax = $200.50 * 5%/100 = 10.025
Lessons: $25*10 = $250
Total cost = 13.5 + 200.5 + 10.025 + 250 = $474.025
