Answer:
<h2>A. x ≤2 or x>6</h2>
Step-by-step explanation:
2x+6 ≤ 10 or 2x + 8 > 20
⇔ 2x ≤ 4 or 2x > 12
⇔ x ≤ 2 or x > 6

Answer:
equilateral triangle: all angles 60°
Step-by-step explanation:
It can be shown easily that an equilateral triangle meets the requirement. It is a little more difficult to show that the requirement forces an equilateral triangle.
In an equilateral triangle, the incenter and the circumcenter are the same point: the centroid. The centroid is half as far from the side as it is from the vertex, so the requirement ri/rc = 1/2 is demonstrated by that property.

Answer:
B
Step-by-step explanation:
A.) If you plug in 5 for t, you'd get -5 squared + 10(5) - 16
Which would equal 25 + 50 - 16 = 59
Answer a says t is less than 5, so for example let's plug in 4. You'd get a lower number, which means its decreasing. A is wrong
B.) Now let's plug in 8 for t.
-8 squared = 64.
64 + 10(8) - 16 = 144 - 16 = 128
Your answer here is positive, and B states is t > 8. Any number above 8 is going to give you a positive number and it is increasing
