30% of the price is $180, so the result after the first drop is $420. The coupon drops another $35, so the final total is $385.
Pretty sure it would be 22.
17+7^2=66
17-2(7)=3 and you would divide 66 by 3
The area of a regular octagon is:
A = a * P / 2, where a is an apothem and P is a perimeter.
P = 8 * 8 m = 64 m
A = 9.7 m * 64 m / 2
A = 620.8 / 2 m²
A = 310.4 m²
Answer:
The area of a regular octagon is 310.4 m².
