Answer:
9 & 18
Step-by-step explanation:
18 - 9 = 9
18 + 9 = 27
The two numbers are '9' and '18'.
Let the both numbers be x and y respectively.
The difference between both the number is 9.
x - y = 9..[1]
The sum of both numbers is 27.
x + y = 27..[2]
Putting value of x from [1] into [2]:
y = 2(x²+3x)
Answer: 4.6 km
a^1 + b^2 = c^2
2^2 + b^2 = 5^2
4 + b^2 = 25
b = sqrt 25 - 4
b = sqrt 21 = 4.6 km
Here is your answer
