I think it's x^4.
(Honestly, I feel 90% positive of this answer, so maybe just get one more opinion!)
The little lines in each side show that the sides are the same length but you also need to find the length of the smaller side which isn’t the same. For this imagine that the shape is split into a square and a triangle and you need to find the long side of the triangle using Pythagoras
a^2 + b^2 = c^2
20^2 + 20^2 = 800
Square root of 800 = 28.3
Then do 28.3-20=8.3
So I think the answer is 20+20+20+20+20+8.3=108.3 cm
The answer is no, the side lengths are not persevered. <span />

Answer:
The equation to represent the rate of receding water level is L = 34
.
Step-by-step explanation:
Given as :
The initial level of water in river = 34 feet
The rate of receding water level = 0.5 foot per day
Or, The rate of percentage of receding water level = 50 % per day
Let the level of water after d days = L
Now,
The level of water after d days = initial level of water × ( 
I.e L = 34 × (
∴ L = 34 × 
Hence The equation to represent the rate of receding water level is L = 34
