Answer:
D. 3.2
Step-by-step explanation:
Mid-segment Theorem of a triangle states that the Mid-segment in a triangle is half of the third side of the triangle.
Based on this theorem, we have: TV = ½(RS)
TV = 3n - 2
RS = n + 12
Substitute
3n - 2 = ½(n + 12)
Multiply both sides by 2
2(3n - 2) = (n + 12)
6n - 4 = n + 12
Collect like terms
6n - n = 4 + 12
5n = 16
Divide both sides by 5
5n/5 = 16/5
n = 3.2
Multiplication property of equality
It's 5.. if you're dividing those two from each other
You multiply by 3 everytime
Answer:
(-2, 1) and (6, 1)
Step-by-step explanation:
The standard form equations for a hyperbola are ...

The first form opens horizontally; the second opens vertically. Further, the center-focus distance 'c' is given by ...

The attached figure illustrates the relation between the various parameters and the features of the hyperbola.
__
<h3>7.</h3>
Using the above information and the information in the first attachment, we find ...
(h, k) = (2, 1)
a = 4, b = 2
The vertices are (h±a, k), so are (2±4, 1) = (-2, 1) and (6, 1).
