Step-by-step explanation:
the solutions for a quadratic equation is
x = (-b ± sqrt(b² - 4ac))/(2a)
in our case
a = 1
b = -4
c = k
x = (4 ± sqrt(16 - 4k))/2 = 2 ± sqrt(4 - k)
x1 = 2 + sqrt(4 - k)
x2 = 2 - sqrt (4 - k)
x1 = 2 + x2
2 + sqrt(4 - k) = 2 + 2 - sqrt(4 - k)
2×sqrt(4 - k) = 2
sqrt(4 - k) = 1
4 - k = 1
k = 4 - 1 = 3
x1 = 3
x2 = 1
43 over 100
4/10 is 40/100. 40/100 plus 3/100 is 43/100

Answer:
B. ¾π
Step-by-step explanation:
This radian measure is in the top negative side of the unit circle --> [-x, y].
Move all terms that don’t contain m to the right side and solve. M = 3
