Hello :
<span>the numbers are : x , y
x - y = 4...1)
xy = 96...(2)
by (1) : x = y +4...(*)
subsct in (2) : (y+4) y = 96
y² +4y -96 = 0
(y² +2(2y) +2²) -2² -96 = 0
(y+2)² -100 =0
</span>(y+2)² <span>= 10²
y +2 = 10 or y+2 = -10
y = 8 or y = -12 ( refused : x is positif)
y = 8
</span>subsct in (*) : x = 8+4 = 12
<span> the numbers are : 12 and 8
12-8 = 4 and 12×8 = 96</span>

Answer:
40
Step-by-step explanation:
Plug the 21 into the equation (21 + 19)
At 8 hours of service, the two limousine rental companies charge the same amount.
Step-by-step explanation:
Given,
Initial fee of Executive Limousine rental = $200
Per hour charges of service = $40
Let,
x be the number of hours.
E(x) = 40x+200
Initial fee of Jet Limousine rental = $120
Per hour charges of service = $50
J(x) = 50x + 120
For the charges to be same;
E(x) = J(x)
Dividing both sides by 10
At 8 hours of service, the two limousine rental companies charge the same amount.
