PEMDAS
We start with exponents.
4 x 4 is 16
12 divided by 3 is 4
4 times 5 is 20
20-16 is 4
4 is the answer.
Answer:
C (4,3)
Step-by-step explanation:
Steps to find the circumcenter:
1) Find and Calculate the midpoint of given coordinates or midpoints.
2) Calculate the slope of the perpendicular bisector lines
3) By using the midpoint and the slope, find out the equation of the line

4) Do the same for another line
Solve the equations of two lines to get the intersection point.
The intersection point will be the circumcenter of the triangle.

Answer:
The final answers are x = 1 OR x = -3.
Step-by-step explanation:
Given the equation is x^2 -3 = -2x
Rewriting it in quadratic form as:- x^2 +2x -3 = 0.
a = 1, b = 2, c = -3.
Using Quadratic formula as follows:- x = ( -b ± √(b² -4ac) ) / (2a)
x = ( -2 ± √(4 -4*1*-3) ) / (2*1)
x = ( -2 ± √(4 +12) ) / (2)
x = ( -2 ± √(16) ) / (2)
x = ( -2 ± 4 ) / (2)
x = (-2+4) / (2) OR x = (-2-4) / (2)
x = 2/2 OR x = -6/2
x = 1 OR x = -3
Hence, final answers are x = 1 OR x = -3.
