Answer: The correct option is (A). When the radicand is negative
Step-by-step explanation: We are given to select the correct option by which we can tell that a quadratic equation has no real solutions.
We know that for the quadratic equation
the radicand is given by
Based on the radicand "D", we have the following rules:
(i) If D > 0 (positive), then the two solutions are real and unequal.
(ii) If D = 0, then the two solutions are equal.
(iii) If D< 0 (negative), then the two solutions are complex (not real).
Thus, when the radicand is negative, then the quadratic equation has no real solutions.
Option (A) is correct.

Step-by-step explanation:
5C5
= 5! / (5! (5 - 5)!)
= 5! / 5! 0! (0! =1)
= 1/1
= 1

Answer:
c.) 57 cm
Step-by-step explanation:
The centroid divides the median into parts with a 2:1 ratio.
OM : OP = 2 : 1
OM : MP = 2 : (2+1) = 2 : 3
As a fraction with MP on top, this is ...
MP/OM = 3/2
MP = (3/2)OM = 3/2×(38 cm)
MP = 57 cm

<em>Comment on the answer choices</em>
Often, you can eliminate a number of the choices in a multiple-choice question just by testing whether they are reasonable. Here, the longer part of a line segment has length 38, so the whole segment will not be shorter than that. The choices 19 and 25.5 make no sense.
The remaining choices are 114 cm and 57 cm. The former is 3 times the length of the given segment, which the drawing tells us is unreasonable.
The only reasonable choice offered is 57 cm.
