Step 3 x + 3x + 2 = 5x + 10
Step 4 x? - 2x - 80
Step 5
(x + 2)(x - 1) = 0
Step 6
x=-- 2.x = 1
In which step, if any, did Freyja introduce the possibility of an extraneous solution? Explain your answer.
Respond in the space provided

a triangular prism is a 3 dimensional shape composed of triangles and rectangles. it is made from two triangular bases and three rectangular sides.  

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)
