A table is 6 feet long and 3 feet wide. You extend the table by inserting two identical table leaves. The longest side length of each rectangular leaf is 3 feet. The extended table is rectangular with an area of (18+6x) square feet.

Write an expression in simplest form that represents the length (in feet) of the extended table.

Answer:

(18+6x)=(6+2x)*3 = Area
length = 6 + 2x
