the complete question is
A rectangular gym has an area of 4x^2 ft². The school decides to add a new weight room. The total area of the gym and the weight room is (4x² + 520) ft². What does
the constant term represent in terms of this problem?
let
AT-------> area total of the gym and the weight room
G------> area of the gym
W-----> area of the weight room
we know that
G=4x² ft²
AT=(4x²+520) ft²
W=?
AT=G+W------> W=AT-G-----> W=(4x²+520)-(4x²)----> W=520 ft²
therefore
the constant term represent the area of the weight room
the answer is
the constant term represent the area of the weight room
