Answer:
0
Step-by-step explanation:
The mode of anything is positive. Two positive values will result in the more than 0. Hence, answer is 0. The 0 + 0 = 0
This is incorrect
-a = b
a + c = d
b + c = d is incorrect because it says a + c and not -a + c.
If you multiply the first line with -1 then you would get a = -b
So the final line would actually be -b+c=d
For the last on you need to set up a proportion with the degrees. You know the arcs add to 360 and that small section is 120 so you set it equal to x over the entire area. X is the answer. The formulas are next to all answers
