The length of a rectangle is 20 units more than its width. The area of the rectangle is x4 - 100.Which statement about the width of the rectangle is true?x2 – 10 because the area expression can be rewritten as (x2 – 10)( x2 + 10) which equals (x2 – 10)((x2 – 10) + 20).x2 + 10 because the area expression can be rewritten as (x2 + 10)( x2 – 10) which equals (x2 + 10)((x2 + 10) – 20).x2 – 30 because the area expression can be rewritten as (x2 + 10)( x2 – 10) which equals (x2 + 10)((x2 – 30) + 20).x2 + 30 because the area expression can be rewritten as (x2 – 10)( x2 + 10) which equals (x2 – 10)((x2 + 30) – 20).
