Alright, lets get started.
Suppose the original deck size: width = x feet
the width is one-fourth the length given in question means length = 4 x feet
Means the originally area =
Now the dimensions are changed.
New dimensions, width = (x + 6)
new length = (4x+10)
So, new area will be =
the area of the new rectangular deck is 128 ft2 larger than the area of the original deck, means
Subtracting from both sides
Subtracting 60 from both sides
Dividing 34 in both sides
Means width = 2 feet
Length would be = 4 time width = 4 * 2 = 8 feet
Means dimension of original deck would be = 2 feet and 8 feet :Answer
Hope it will help :)

<em /><em />
Step-by-step explanation:
Given
In 1990; Income= $39000
In 2010; Income= $70768
Solving (a): An equation in form of f(x) = ax + b
First, we need to determine the slope, a
Taking y as income and x as year index.
When x = 0; y = 39000
When x = 20; y = 70768
Substitute these values in the above formula
Next, is to determine the formula using:
<em>Considering :When x = 0; y = 39000, we have</em>
<em /><em />
<em /><em />
<em>Make y the subject of formula</em>
<em /><em />
<em />
<em>Express y as a function of x</em>
<em /><em />
Solving (b): Income in 2005
<em>In 2005, x = 15</em>
So:
