15x12=180
180$ simple unless u have a different way to do it
Answer:
- The two solutions are:

- The next and every step are below.
Explanation:
1.
: Given (addition property / add - 3 to both sides)
2.
: Given (commom factor - 2)
3. 
To obtain the perfect square it was added the square of half of the coefficient of x: (1/2)² = 1/4, inside the parenthesis.
Since, the terms inside the parentthesis are multiplied by - 2, you have to add - 2 (1/4) = - 1/2 to the left side of the equation.
4. Now, you have that the trinomial x² - x + 1/4 is a square perfect trinomial which is factored as (x - 1/2)² and get the expression:

5. Divide both sides by - 2 to get the next expression:

6. The last step is to extract squere root from both sides of the equality:

Answer:
14.5 × 3.18 - 14.5 x 1.88
You paid $18.85 more in june than in February
Step-by-step explanation:
In order to find the answer to this question you will need to find how much you paid in June and how much you paid in February.
ex.14.5 x 3.18 - 14.5 x 1.88
To solve this you need to find the product of 14.5 x 3.18 and 14.5 x 1.88 and then subtract them from eachother.
ex.14.5 x 3.18 =46.11
14.5 x 1.88=27.26
46.11-27.26=18.85
