Dont u have a calculator
Step-by-step explanation:
1) if (0;0) if point A, (1;2) is point B; (-1;-2) is C, (2;1) is D, then
2) the vector AB is (1;2); vector AC is (-1;-2) and vector AD is (2;1), then
3) the length of AB, AC and AD are:



4) if the lengths above are equal, then it means that (0, 0) is equidistant from (1, 2), (-1, -2) and (2, 1).
Answer:
m= 67.5 and n=56.25
Step-by-step explanation:
180-15=165
165/2= 82.5
90-15= 75
75+75= 150
180-150=30
30+82.5= 112.5
180- 112.5= 67.5
m= 67.5
180-67.5= 112.5
112.5/2= 56.25
n= 56.25
6ax is a common factor, so divide top and bottom by 6ax:
(a-3x+7ax)/6ax.
Divide each of the terms in the numerator by the denominator:
1/6x-1/2a+7/6
