Answer:
x=34
Step-by-step explanation:
x+(x+12)+(100) = 180
2x+112=180
x=68
x=34
14 tiles would be able to go on that one side of the counter
Answer is A) -1 because it they are parallel then they have the same slope. If the green line has a -1 slope so does the red line
Number of solutions: no roots
Type of solution: Not Real
Step-by-step explanation:
We need to identify the number of solutions and their types using the discriminant.
We are given: 
Rearranging:

Discriminant can be found by: 
where b=-40, a=10 and c=41
Putting values:

So, Discriminant is -40
If the discriminant is less than zero i.e -40 then there are no real roots.
So, Number of solutions: no roots
Type of solution: Not Real
Keywords: discriminant
