Answer:
21x + 29y - 8
Step-by-step explanation:
(−7x+8x+19y)−(6y+8−20x−16y)
−7x+8x+19y−6y-8+20x+16y
(−7x+8x+20x)+(19y−6y+16y)-8
21x + 29y - 8

Answer:
B. 9/20
Step-by-step explanation:
the circumference is 2r. Since the radius is one, that would be 2.
81/360=0.225, or 22.5% of the circumference. 22.5% of 2 is 0.45. 0.45=9/20, so the answer is B.
CHECK: 2 = 6.283
6.283x0.225=0.14137, or 9/20
