Question A rectangle has a length represented by the function f(x)=x and a width represented by the function g(x)=x+3 where both functions are in feet.

Question

(f⋅g)(x)=x2+3x ; It represents the perimeter of the rectangle in feet
(f⋅g)(x)=x2+3x ; It represents the area of the rectangle in square feet.
(f⋅g)(x)=4x+6 ; It represents the perimeter of the rectangle in feet.
(f⋅g)(x)=4x+6 ; It represents the area of the rectangle in square feet.

Answer 1

(f⋅g)(x)=4x+6 ; It represents the perimeter of the rectangle in feet.
