Answer is 17.647 or if rounded 18
The expression is

and the simplified form is

good luck


a² + b² = c²
40² + b² = 41²
b² = 41² - 40²
b² = 1681 - 1600
b² = 81
b = 9
slope (m) of asymptote = 
y-intercept (b) = 0 since the center is at the origin
Answer: y =
and y = 
Answer: 16, 10, 64
Step-by-step explanation:
64/4=16, so the 3rd number is 4x the first.
16-6=10. 6 less than the first number.
16+10+64=90.
Take 12 and divide it by 3 to get the number of slices per quarter. Then multiply the answer you got by four. The answer is 16.
