Answer: No, they are not.
Step-by-step explanation: To see if ratios are equivalent, you have to simplify them. 6:4 can be simplified to 3:2 but 19:12 cannot be simplified anymore. Since 3:2 is not equal to 19:12, they are not equivalent.

FOIL
i x i = -1
(27 + 6i - 45i +10) - (27 +3i - 45i +5)
Combine like terms and distribute the negative
37 - 39i + 42i - 32
3i + 5
This is the farthest I could go with it. Assuming you were looking for a simplification though you did not specify your desired answer's criteria. Hope this helped!</span>
Answer:
$3600
Step-by-step explanation:
Cost of the car = $8000
The car loses value at 11% each year .
That’s
11% /100% x $8000
0.11 x 8000
$880
11% decrease each year means that the cost of the car is reduced by $880 per year.
Therefore,
Worth of the car in 5 years
= $8000 - ($880 x 5)
= $8000 - $4400
= $3600
The car will be worth $3600 in five years
804 miles/12 hours = 67 miles
Which means that Ivan drove 67 miles per hour
67 miles*9 hours = 603 miles
Which means that in 9 hours Ivan can drive 603 miles if he drives at a constant speed of 67 miles per hour.
Seven hours and 5 minutes
