Answer:
4(3n + 2)
Step-by-step explanation:
as we know perimeter of a square is 4 x side
one side is 3n + 2
4 sides = 4(3n +2)
A rectangular prism<span>, any pair of opposite faces </span>can<span> be </span><span>bases</span>
Area of the base = pi*(4x+2)^2 = pi*(16x^2 +16x +4)
volume of cylinder = pi*r^2 *h
V = pi *(16x^2 +16x +4)(5x+4) = pi*(80x^3 +80x^2 +20x +64x^2 +64x +16) =
= pi*(80x^3 +144x^2 +84x +16)
than we consider it without pi so result choice A. is right sure

Emily gave Jake 20% of the buttons. 20% = 15 buttons, and 15 x 5 = 75
52=100%
x=30%
52/x=100%/30%
which equals to 15.6
Answer 15.6
