An equilateral triangle has a perimeter of 12x+ 18 units. Which expression can be used to show the length of one side of the triangle?
6(2x+3): Each side length is 2x+ 3 units.
3(4x+6). Each side length is 4x+6 units.
2(6x+9). Each side length is 6x+9 units.
x(12+ 18). Each side length is 12+ 18 units.

given : the shape of his satellite can be modeled by   where x and y are modeled in inches.

now,the given equation   is a equation of parabola.

here, coefficient of x is positive, hence the parabola opens rightwards.

on comparing this equation with standard equation , we get

in standard equation, coordinates of focus=(0,m)

thus for given equation coordinates of focus=(0,1.5)

step-by-step explanation:

noncoplanar points are points that do not lie on the same line.

it goes right
