Answer:
0 solutions
Step-by-step explanation:
2n + 4 = 4n + 1 - 2n
↑
first combine like terms (right side)
2n + 4 = 2n + 1
but this part you can tell that there's 0 solutions, because both sides have 2n/ same variable with same number.
8/5 = 20/x
8x = 20(5)
8x = 100
x = 12.5

The area of the shaded region is the quarter circle minus the isosceles right triangle. The area of quarter-circle is pi*r^2/4=pi*8^2/4=16pi. The area of triangle is 8*8/2=32, so the area is 16pi-32.
The perimeter of the shaded region is the length of arc plus the segment. The length of arc is pi*2r/4=pi*16/4=4pi, and the length of the segment is 8*\sqrt(2) according to pythagorean's theorem. The total perimeter is 4pi+8*\sqrt(2).
