Answer:
x = -5/2 + i√19 and x = -5/2 - i√19
Step-by-step explanation:
Next time, please share the possible answer choices.
Here we can actually find the roots, using the quadratic formula or some other approach.
a = 1, b = 5 and c = 11. Then the discriminant is b^2-4ac, or 5^2-4(1)(11). Since the discriminant is negative, the roots are complex. The discriminant value is 25-44, or -19.
Thus, the roots of the given poly are:
-5 plus or minus i√19
x = -----------------------------------
2(1)
or x = -5/2 + i√19 and x = -5/2 - i√19
Odd integers are 2 apart from each other (in between them is an even number)
x and x+2 is answer
5600 is 100 times larger than 56
Angle B = 54°
Step-by-step explanation:
complimentary means they add up to 90
54 + 36 (angle A) = 90
also x= 51
