Step-by-step explanation:
(x+2y)²=x²+4xy+4y²
...........
Wow I don't get it either but my guess would be 9,6...sorry....
Your line is wrong from the start. But for the equation:
Circumference = 2 x radius x Pi
Circumference = 2 x 0.8 x pi
Circumference = 1.6pi or 5.024 yards
area = r^2 x pi
Area = 0.8^2 x pi
Area = 0.64pi or 2.0096 square yards
Answer:
4/5 times a number Plus 8 answer=b
cuz if you because it says 4 / 5 which would be X so you have to do for as 5 as fraction and then you have to multiply it
