$25,000 is the answer you would take $620,000 x 0.04 (4%)= 24,800 which rounds to 25,000
1) the polynomial representing the area is
2x^4 + 6x^3 - 5x^2 -7x + 24
2) the constant term is
24
3) the polynomial is a 4th degree
4) if my guess is ryt... the LEADING coefficient is the coefficient of the highest degree of X ...i.e 2
If I could get more context then that would help. Because an exponent being an odd number doesn’t do anything, so it could be either a negative or a positive
