Answer:
Width = 15 inches Length = 20 inches
Step-by-step explanation:
The area of a rectangle is calculated using the following formula.
(1)
Where L is the length and x is the width of the rectangle
In this case we know that the length of the rectangle is 5 inches greater than its width. This means that:
(2)
Also The area of a rectangle can be represented by the equation 
so to find the width x we solve the equation
(3)
For an equation of the form
the quadratic formula is:

In this case note that:

Then:




→ 
→ 
We take the positive solution 
Now we use equation (2) to find L

Answer</h2>
The value of x is 20
<h2>
Expalantion</h2>
As given in question

We have to determine the value of x
So, by taking LCM of given equation

By taking 10 to other side of equation




x = 20
Answer:
<h2>The value of a is 12.</h2>
Step-by-step explanation:
The equation is given by (a - 12)x = a + 8.
In order to get the solution of the equation, that is the value of x, the above equation is needs to be divided by a - 12. (a - 12) will be in the denominator.
The solution can not be found, if the value of a - 12 will be 0, that is a = 12.
