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
Answer:

Step-by-step explanation:
I might not be right, never done this kind of math before. Just taking a guess.
Answer:
Three times the sum of a number and 2.
Step-by-step explanation:
Sum of a number and 2 = x + 2
3 times = 3 multiplied
Let x = the price for theater ticket
so, x + 60 = 450
x = 390
there are 15 members in the club so 390/15 = $26 per person
