Answer:
Option : The product of the roots is - 4
Step-by-step explanation:

Therefore the roots are -4 and 1
The product of the roots are -4 x 1 = -4
$500 < or = $415 + d
(subtract the 415 from both sides)
$85 < or = d
5x + 4x = 720
9x = 720 (divide by 9)
X= 80
In order to get the bigger ratio, which is 5, you would substitute x for 80. (I'm bad at explaining)
Work:
5(80)= 400
Answer:
The new volume is 4 times the old volume ♡
