Answer:
2
Step-by-step explanation:
we will find the discriminant of the equation
d = b^2 - 4ac (here, a = 1 , b = 3 , c = 1. from the general formula: ax^2 + bx + c)
d = 9 - 4
d = 5
since d > 0, the roots are real and different
hence, the both the roots of this equation are equal
Answer:
5. C
6. A
Step-by-step explanation:
To find the answer, plug in the x- and y-values into each equation. When the equation comes to be true that is your answer.
So for question 5, you plug -5 into the x and 13 into the y for each equation. The first equation will give you an answer of 13 = -7, which isn't true.
The second will give you 13 = 7, so you keep going.
The third gives you 13 = 13, which is true, so that one must be the answer.
Do this for every question and it will give you the answer.

<h2>60,47,73</h2>
Step-by-step explanation:
Let the first angle be 
degrees
Let the second angle be 
degrees
Let the third angle be 
degrees
It is given that sum of angles is 
degrees.
so,
...(i)
It is given that sum of the measures of the second and third angles is two times the measure of the first angle.
...(ii)
It is given that the third angle is 26 more than the second.
...(iii)
using (ii) and (iii),
using (i),(ii) and (iii),
