Between 198 and 200, I believe.
Answer:
No real solutions.
Step-by-step explanation:
We need to solve the following equation: 3x^2 + 6x + 6 = 0
First, we should divide the whole equation by 3:
3x^2 + 6x + 6 = 0 ⇒ x^2 + 2x + 2 = 0
Now, the equation has no real results. It happens because the polynomial never crosses the x-axis. (See graph attached).
The imaginary solution is:
x = -1 + i
x= -1 - i
Answer:
Answer is; Evaluating
Step-by-step explanation:
Student self-assessment involves students evaluating their own work and learning progress.
Through self-assessment evaluation, students can:
* See where their knowledge is weak
* See where to focus their attention in learning.
* Set realistic goals
* Revise their work
* Track their own progress.
In Rachel's case, after writing her midterm exams, she already set her goal grade. So when she got her midterm grades, she needed to evaluate her work to find out her performance.
Therefore, according to the question, Rachel is EVALUATING her performance.
Multiply both sides by 12 to get a = 240
