Answer:
1. In order for Pattern B to be linear, the common difference of the number of dots between each step should be constant. As it is not constant, the pattern is not linear.
2. In order for Pattern B to be exponential, the common ratio of the number of dots between each step should be constant. As it is not constant, the pattern is not exponential.
3. In order for Pattern B to be quadratic, its sequence of second differences must be constant.
First differences:

Second differences:

Therefore, as the sequence of second difference is constant, the patten is quadratic.
The function for pattern B is: 
(where x is the step number)
Answer:
m+n=140
Step-by-step explanation:
So the angles in a triangle always add up to 180. We already know that the first angle in the triangle is 40 degrees because it's shown in the angle below the triangle. So we have 140 degrees left since 40 is taken up. That eans m+n=140
1 2/3 divided by .8 is 2 and 1/12 so the answer is C
Step-by-step explanation:
