Answer:
A)
Step-by-step explanation:
the solution of a squared equation is
x = (-b ± sqrt(b² - 4ac)) / (2a)
in our case
a = 1
b = 8
c = 22
x = (-8 ± sqrt(64 - 88))/2 = (-8 ± sqrt(-24))/2 =
= (-8 ± sqrt(4×-6))/2 = (-8 ± 2×sqrt(-6))/2 =
= -4 ± sqrt(-6) = -4 ± i×sqrt(6)
Answer:
3750
Step-by-step explanation:
50*70=35005
5*50=250
X=270 units
270 units can be manufactured per month
Answer:
x < 1/4
Step-by-step explanation:
It has a rotational symmetry of 6
So minimum number of degrees = 360 / 6
= 60 degrees
