For this case suppose that we have a quadratic equation of the form:

The solution to the quadratic recuacion is given by:

Where,
The discriminant is:

When the discriminant is greater than zero, then the root is positive, and therefore, we have two positive real solutions.
Answer:
B. it has two real solutions
Answer:
The measure of angle 2 is 52°.
Step-by-step explanation:
Consider the below figure attached with this question.
It is given that

and x=6.
From the below figure it is clear that Lines 1,2 and 3 intersect each other at a point and form 6 angles.
It is clear that angle 2 and angle 5 are vertical opposite angles because these angles created by intersection of line 2 and line 3.
If two lines intersect each other then vertical opposite angles are congruent.
(vertical opposite angles)

Substitute x=6.



Therefore, the measure of angle 2 is 52°.

Expression:
0.5m - 0.75n = 16 (1/2m - 3/4n = 16)
------------------------------------------------
Solution:
0.5m - 0.75n = 16
0.5m - 0.75(8) = 16
0.5m - 6 = 16
0.5m - 6 + 6 = 16 + 6
0.5m = 22
0.5m/0.5 = 22/0.5
m = 44
