Hello :
the common ratio is r = -95-(-100)=5
the general terme is : un= u1+(n-1)r
un = -100 +(n-1)(5)
un =-100 +5n-5
un = 5n-105
The last term is : 100
un =100
5n-105 = 100
5n =205
n = 41 (Number of terms)
The last term is : u 41
<span>the sum is : S= (41/2)(-100+100)=0</span>
Answer:

Step-by-step explanation:
First, we calculate the unknown angle of the left triangle and right triangle:
Unknown angle for left triangle⬆️

Unknown angle for right triangle⬆️
Now we've calculated the two angles for the small triangle in the middle. So, we just have to calculate the top angle of the middle triangle:

The angle 65° and angle of x are vertical angle.(both are equal)
So... <u>x= 65°</u>

Answer:
The equation showing this situation is 
Step-by-step explanation:
Given : A quadratic equation of the form
has one real number solution.
To find : Which could be the equation?
Solution :
A quadratic equation in form
has a solution
called a quadratic formula in which the roots are one real,two real or no real is determine by discriminant factor.
Discriminant is defined as to determine the number of roots in a quadratic equitation has following rules :
1) If
there are two real roots.
2) If
there are one real roots.
3) If
there are no real roots.
According to question,
A quadratic equation of the form
has one real number solution.
So, The equation showing this situation is
