A triangle is a polygon with three edges and three vertices. It is one of the basic shapes in geometry. A triangle with vertices A, B, and C is denoted △ABC. In Euclidean geometry any three points, when non-collinear, determine a unique triangle and simultaneously, a unique plane. In other words, there is only one plane that contains that triangle, and every triangle is contained in some plane.

Answer:
x = -6 and x = 1
Step-by-step explanation:
It's a little easier to see what must be done here if you write this problem as:
3
(1/2)x = -------------
x + 5
Multiply both sides by 2 to eliminate the fraction 1/2:
6
x = ---------------------
x + 5
Now cross multiply: we get x(x + 5) = 6, or:
x^2 + 5x - 6 = 0, or
(x + 6)(x - 1) = 0, so that x = -6 and x = 1. Both are valid answers, as the given expression is true if you substitute these x-values one at a time

Answer:
Tn = 75+25n
Step-by-step explanation:
The balance are in arithmetic progression
$100, $125, $150...
The formula for calculating the nth term of the sequence is expressed as;
Tn = a+(n-1)d
a =100
d = 125 - 100 = 150 - 125
d = 25
n is the number of terms
Substitute
Tn = 100+(n-1)*25
Tn = 100 + 25n-25
Tn = 75+25n
Hence the nth term of the sequence is Tn = 75+25n
