An isosceles triangle is one where two sides are equal to each other. The third side is of a different length.
At first glance, choice A looks like the answer because we have two sides that are the same length (the sides of length 1). However, this triangle is not possible because 1+1 = 2 which is less then 3. For a triangle to be possible, adding up two sides must be larger than the third side. I'm using the triangle inequality theorem here.
This works for choice D since 6+6 = 12 which is greater than 5. Also 5+6 = 11 which is greater than 6. So the answer is choice D
If this is all there is to the equation it would not have an asymptote.
F(x) =3x+4 is a linear equation and it's domain(possible x values) would be all real numbers. Therefore you would not have a vertical asymptote. This also results in having a range (possible y values) of all real numbers. Again, there would be no horizontal asymptote.
-6p - 3 = 9, Solve for p
Add 3 to both sides.
-6p = 12
Divide -6 by both sides.
p = -2
