Alright, lets get started.
Suppose the original square window has the side = x feet
The new window is 3 ft wider and 2 ft higher than the square one.
Means length of the new window will be =
Width of the new window will be =
So the area of the new window will be =
So the area of the new window will be =
So the area of the new window will be =
As given in question the area of 30 square feet for the new window, hence
Factoring
x = -8 or x = 3
Side could not be negative hence
side of the original square window will be = 3 feet : Answer
Hope it will help :)
Equal expressions can be taken equal to an another variable. The system of equations representing the equation is
When you raise a number with an exponent, there comes a result.
Lets say you get
Then, you can write 'b' in terms of 'a' and 'c' using logarithm as follows
Some properties of logarithm are:
Log with base e = 2.71828... is written as simply.
Log with base 10 is written as simply.
The given equation is:
Adding on both the sides, we get:
The, we get two equations as:
This is the needed system of equations.
