60.
The question gives you the fact that 6 bricks is 2 feet high.
What do you do to get from 2 to 20?
You multiply by 10.
Since you multiplied one thing by 10, you must do it to the other side so it remains balanced.
2 ft x 10ft = 20ft
6 bricks x 10 bricks = 60 bricks
"Completing the square" is a step in the solution of quadratic equations. It can be accomplished without the guesswork or trial-and-error associated with methods like factoring, and it always leads to a solution. It is the method by which the quadratic formula is derived.

Step-by-step explanation:
Answer:
A ) The money which Andre pay for the bike is $ 67.30
B ) The money which Andre pay for the bike is $ 76.92
Step-by-step explanation:
Given as :
The wholesale cost or market price of the bike = m.p = $ 96.15
A ) The discount percentage = 30 %
Let The selling price of the bike after discount = s.p
Now ,
Discount % = 
or, 30 % = 1 - 
or,
= 1 - 
Or,
= 1 - 
or,
= 
Or,
= 
Or, s. p =
× 96.15
∴ s.p = $ 67.305
So, He will pay $ 67.30
Hence The money which Andre pay for the bike is $ 67.30 . Answer
B ) If the bike is discounted by 20 % , let The selling price = s.p'
So,
Discount % = 
or, 20 % = 1 - 
or,
= 1 - 
Or,
= 1 - 
or,
= 
Or,
= 
Or, s. p' =
× 96.15
∴ s.p' = $ 76.92
So, He will pay $ 76.92
Hence The money which Andre pay for the bike is $ 76.92 . Answer
