Klio2033 [76]

Answer:

Formula for area is length times width

So 2x × x = 2x^2

E. G.

2×2×2=8

And can also be written as 2^3

Meaning 2×2×2

So in this instance x × x=x^2

In front of the length x imagine a 1

So 2×1=2

Find the equation of the axis of symmetry of the following parabola algebraically.

mr Goodwill [35]

Answer:

the equation of the axis of symmetry is $x=8$

Step-by-step explanation:

Recall that the equation of the axis of symmetry for a parabola with vertical branches like this one, is an equation of a vertical line that passes through the very vertex of the parabola and divides it into its two symmetric branches. Such vertical line would have therefore an expression of the form: $x=constant$ , being that constant the very x-coordinate of the vertex.
