X= 100°
180° - 57° = 123

x = 100°
Answer:
- Prime: 3
- GCF: 1
- Factoring Trinomials: 4
- Difference of Squares: 2
- Perfect Square Trinomial (PST): 5
Step-by-step explanation:
1. Each term has an even coefficient, so a factor of 2 can be removed:
2(3x^2 +7x -15)
The remaining quadratic factor is prime.
__
2. Each of these two terms is a square, so this is the difference of two squares.
__
3. This cubic has one irrational negative real root. It is prime.
__
4. This trinomial factors in the usual way: (x +15)(x -2). It is factored by "factoring trinomials."
__
5. The magnitude of the x-coefficient is double the square root of the (positive) constant, so this is a perfect square trinomial.
Answer:
- Unit price of a 2-liter bottle of soda:

- Unit price of a case of twelve 12 ounce cans:

- The better bargain is the case of 12 ounce cans.
Step-by-step explanation:
Let be "x" the unit price (price/ounce) of the soda in the 2-liter bottle and "y" the unit price (price/ounce) of the soda in the case of twelve 12 ounces cans.
According to the data provided in the exercise, you know that:
1. The 2-liter bottle of soda is equal to 67.6 ounces.
2. That bottle costs $1.89
Then, the unit price is:

3. There are 12 ounce cans in the case. Then the total ounces is:

4. It costs $2.99. So the unit price is:

Since:

The better bargain is the case of 12 ounce cans.
