b or the second option
The correct answer for the question that is being presented above is this one: "w(w + 2) = 48." John has 48 square centimeter tiles he wants to use to create a mosaic. He wants the mosaic to be rectangular with a length that is 2 centimeters longer than the width.
Let w = width
Let (w+2) = length
Area = w(w+2).
Its already in simplest form but you can convert it to a mixed fraction and get:
1 5/8
When you have a negative exponent, you move it to the other side of the fraction to make the exponent positive.
For example:
or 
or y²
So:
Your answer is B
