Answer:
29%
Step-by-step explanation:
I guarantee this is the right answer.
In a regular hexagon, each side is contained in a separate equilateral triangle with side of 2-units. That makes six equilateral triangles with side 2-units.
Further, each equilateral triangle of side 2-units contains four (4) equilateral triangles of side 1-unit.
Therefore the total number of equilateral triangles of side 1 units in a hexagon with side two units is 6*4=24.
The odds are one in three hundred twelve.
=1/312
the first answer is -7/15
the second answer is 1/2
Second binomial formula
(a - b)^2 = a^2 - 2ab + b^2
(3x - 4)^2 = (3x)^2 - 2 × 3x × (-4) + (-4)^2
=9x^2 + 24x - 16
