It would be multiplied by 1 because they're the same number
Answer:
The standard from of the expression is: 
Step-by-step explanation:
Here the given expression is :

Now, the standard form of a circle is given as :

Here, (h,k) = Coordinates of Center, r = Radius
Also, use the algebraic identity:

Now, converting the given expression in the standard form, we get:

Add 2 on both sides of the equation, we get:

So, here the standard from of the expression is:

Center coordinates here are (h,k) = ( -1 ,1) and Radius = 2 units
1 by 8 rectangle... that is a area of 8 square inches.
the greatest is 4 by 5 that is a area of 20 square inches.
The difference is 12
