Answer:
1.
2. 
Step-by-step explanation:
1. The area of a hexagon is A = 
Here our a is 4, so plugging in 4 to our equation gives
which simplifies to 
2. The area of an octagon is 
Here our r is 9, so plugging in 9 to our equation gives
which simplifies to 
The three consecutive integers are 127, 128, 129
1/2+-2/5t(+2/5)=1/5t+t(+2/5)
simplify
1/2=2 and 3/5t
change to a decimal
.5 = 2.6t
divide both sides by 2.6
.5/2.6 2.6t/2.6
you get T= .3125
