No. If you subtract a negative from a positive number its equivalent to adding the inverse of that negative number. If you add a negative to a positive number It is equivalent to subtracting from that positive number.
Answer:
Step-by-step explanation:
givens
x1 = 3
x2 = 4
y1 = 4
y2 = 7
formula
d = sqrt( (x1 - x2)^2 + (y1 - y2)^2 )
solution
d = sqrt( (3 - 4)^2 + (4 - 7)^2 )
d = sqrt ( 1 + 3^2)
d = sqrt( 1 + 9)
d = sqrt( 10)

========================================================
Explanation:
For any inscribed quadrilateral like this, the opposite angles are always supplementary. This means the angles add to 180
B+D = 180
(2x-1) + (3x-59) = 180
(2x+3x) + (-1-59) = 180
5x-60 = 180
5x = 180+60
5x = 240
x = 240/5
x = 48
Use this x value to find angle A
A = 2x+4
A = 2*48+4
A = 96+4
A = 100
This then means,
A+C = 180
C = 180-A
C = 180-100
C = 80 degrees
Side note: The term "cyclic quadrilateral" is the same as "inscribed quadrilateral".
