Step-by-step explanation:
step 1
Find the area of one button
The area is equal to
we have
---> the radius is half the diameter
Convert to meters
assume
substitute
step 2

Answer:
2y^3-7y^2+7y
Step-by-step explanation:
7y - 2y^3 + 5y^2 - ( 12y^2 – 4y^3)
Distribute the minus sign
7y - 2y^3 + 5y^2 - 12y^2 + 4y^3
Combine like terms
2y^3-7y^2+7y
Step-by-step explanation:
there 5^(n+1) + 5^(n+2) = 5^n x 5^1 + 5^n x 5^2 breaking them as x^(a+b) = x^a x x^b
then taking common 5^n from both terms
480 bottles because 300 divided by 5 is 60 so then you multiply 60 by 8 and you get 480!
