We can solve this equation by using the Square Root Method.
First, take the square root of each side of the equation:
(x-8)^2 = 144 becomes x-8 = 12
Then add 8 to both sides.
x=20
The original lawn was d. 20 feet by 20 feet.
Answer: There are 1436 bricks that he will need to make a brick wall.
Step-by-step explanation:
Since we have given that
Dimensions of a brick wall is given by
Length = 14.5 feet
Width = 0.5 feet
Height = 5.5 feet
Dimensions of a brick is given by
Length = 6 inch
Width = 4 inch
Height = 2 inch
We need to find the number of bricks :
So, Number of bricks is given by

Hence, there are 1436 bricks that he will need to make a brick wall.
In all these expressions you have a power of a power.
You can solve them simply multiplying the exponents.
Remember that any quantity raised to the zero is equal to 1.

"<span>The volume of a cylinder with height h and radius r is given by the formula below. V = Πr 2 h Complete the equation below by writing an equation equivalent to height, h, of a cylinder.
Please, instead of "</span>V = Πr 2 h," type V = pi*r^2*h: "pi times radius squared times h"
V
This can be solved for the height of a cyl.: h = ---------
pi*r^2
Use " ^ " to denote exponentiation, please.
