Answer 2

Answer:

$R(x)= 20x^2+300x+1080$

Step-by-step explanation:

The number of teams who entered in  basketball tournament

$T(x)=4x+24$

The entire fee paid by each team to enter the tournament

$F(x)=5x+45$

Total entry fees = Number of teams * fee paid by each term

$R(x)= T(x) * F(x)$

$R(x)= (4x+24) *(5x+45)$

USe FOIL method to multiply it

$R(x)= 20x^2+180x+120x+1080$

combine like terms

$R(x)= 20x^2+300x+1080$
