Answer:

Step-by-step explanation:
The division problem given to us is
.
To perform the synthetic division, we write out the coefficient of the polynomial. We set the linear factor to zero and solve for x, this becomes our divisor. That is
.
We carry out the synthetic division as shown in the attachment.
The result of the synthetic division is 4 -27 167 -996
The first three terms are the coefficients of the quotient and the last term is the remainder.
Therefore the quotient is
and the remainder is
.
The dividend, the quotient and the divisor are written as

The correct answer is A
Answer: 
Step-by-step explanation:
Let be "x" the amount of gasoline in liters that the car's tank had at the beginning of the trip.
1. In the first part of the trip the amount of gasoline the car used can be expressed as:

2. After the first part of the trip, the remaining was:
3. In the second part of the trip the car used
of the remaining. This is:

4. The total amount ot gasoline used in this trip was 20 liters.
5. Then, with this information, you can write the following equation:

6. Finally, you must solve for "x" in order to find its value. This is:
