Answer:
an + 1 = an + 2n -1 ,a 1=1
a8= 50
Step-by-step explanation:
an+1=an+2n-1,a1=1
a6=a5+2x5-1
a6=26
a7=26+11
a7=37
a8=37+13
a8=50
Answer:
201.1 km²

Answer:
5
Step-by-step explanation:
To solve for hypotenuse we use the Pythagorean theorem:

In this theorem:
c= hypotenuse
a = leg
b = leg
Substitute into theorem:



(square root both sides)

Therefore the hypotenuse has a length of 5.
Please say thanks if correct :)
