The area of a surface is the number of square units present in the surface. For a rectangle, it is calculated from the product of the length and the width. To determine the length and width of the lot given above, we first assume that it is in a rectangular shape which is defined by its length and its width. We are given the following:
Area = 4200 square feet
Length = 4x - 20 feet
Width = x feet
From the definition of the area of a rectangle,
Area = length x width
4200 = (4x -20) (x)
4200 = 4x^2 - 20x
4x^2 - 20x - 4200 = 0
4(x^2 - 5x - 1050) = 0
x^2 - 5x -1050 = 0
Factoring the equation would lead to:
(x - 35) (x +30) = 0
x -35 = 0 ; x = 35
x + 30 = 0 ; x = -30
The width should not be a negative value so the width would be equal to 35 feet. So, the length would be
Length = 4(35) - 20 = 120 feet

You are suppose to add up all the numbers then divide it by how many numbers are there.
Answer:
x = 2
Step-by-step explanation:
2(x+1)=3x
2x+2=3x
2x - 3x=-2
-x=-2
