For a big dinner, Savannah needs to attach an extra piece to her dining room table without the extra piece. The table is 6 feet long and 3 feet wide attaching the extra piece to the table add X feet to its length pick all the expressions that represent the area of the table with the extra piece number one is X (6+3) number two is 3(6+x) number three is 18+ 3X and number four is 18+ 6X pick all the expressions that represent the area of the table with the extra piece

The correct answer is number two: 3(6+x). This expression represents the area of the table with the extra piece because the length of the table is still 6 feet, and the additional piece is attached to the width, making it x feet longer. Thus, the area is the length multiplied by the width: 6 * (3+x) = 18 + 3x.
