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:
the coefficient of the 2nd term: - 38
Step-by-step explanation:
V = 2x (4x + 1) (5x - 6)
=(8x² + 2x) (5x - 6)
= 40x³ - <u>38</u> x² - 12x
