Answer:

15

Step-by-step explanation:

let r represent red marbles then white = 2r + 5 and total is 20, thus

r + 2r + 5 = 20 ( subtract 5 from both sides )

3r = 15 ( divide both sides by 3 )

r = 5 ← number of red marbles

Thus number of white = 20 - 5 = 15

The attendance for a team's basketball game can be approximated with the polynomial -5x^2+80x+285, where x is the number of wins
Elan Coil [88]

Answer:

The attendance when the team won 4 games in the previous month is 525

Step-by-step explanation:

The attendance for a team's basketball game can be approximated with the polynomial : -5x^2+80x+285

x represents the number of wins the team had in the previous month.

Factor the polynomial :

-5x^2+80x+285

-5(x^2-16x-57)

-5(x^2-19x+3x-57)

-5(x(x-19)+3(x-19))

-5(x+3)(x-19)

Substitute the value of x = 4

The attendance when the team won 4 games in the previous month = -5(4+3)(4-19)=525

Hence The attendance when the team won 4 games in the previous month is 525
