Answer:
Step-by-step explanation:
Consider polynomial 
If x=-2 is its zero, then you can divide the polynomial 
by 
and get
If x=-1, then the polynomial can be rewritten as
The quadratic polynomial has roots
Then the polynomial has zeros
First, let's simplify the inequality
The graph looks like this:
Notice that the white dot is placed above the -6, it is important to include it like that.
Now, as an interval:
1: 8 faces and 9 with the base 9 vertices and 16 edges
2: 3 faces and 5 with the bases 6 vertices and 9 edges
3: 3 faces and 4 with the base 4 vertices and 6 edges
8y + x + 12
other then that, you cannot further simplify this, nor can you factor because the greatest common factor for all of them is just 1
<h3>Answer:</h3>
12 students
<h3>Explanation:</h3>
40% earned a B; 20% earned an A, so (40%+20% =) 60% got a "B or better."
60% of 20 students is ...
... 60/100 × 20 students = 1200/100 students = 12 students
