The union of three segments determined by three noncollinear points. scalene triangle 2. a triangle in which no two sides have the same length. acute triangle 3. a triangle in which at least two sides have the same length. right triangle 4. a triangle in which all three sides have the same length. triangle 5. a triangle in which all three angles are acute. obtuse triangle 6. a triangle in which one angle is obtuse. equiangular triangle 7. a triangle in which one angle is a right angle. equilateral triangle 8. a triangle in which all angles are equal. isosceles triangle

if the eqn of the parabola is f(x) = (x-4)(x+2), we need to mult. this out to find the coordinates of the vertex.

then f(x) = x^2 + 2x - 4x - 8, and f(x) = x^2 - 2x - 8.

one way in which you can find the vertex is to calculate x = -b / (2a).   here, that comes to

        )

x = = 1.   f(1) = 1^2 - 2(1) - 8 = - 9.   vertex is at (1, -9).

        2(1) 

find another point on the curve:   let x=0, for which y=-8.   then (0, -8) is on the curve.   plot the vertex and this point and draw a smooth parabola thru both.

hope this

i believe the answer is 68cm

step-by-step explanation:

i just took 34 x 2 because the space between v and y is the same as y to k.
