Please simplify the following equation and show how: (2x+2)^3

Natasha_Volkova [10]

You can use (a+b)2 = a2+2ab+b2.
(2x - 3)2 = (2x)2 + 2(2x)(-3) + (-3)2 = 4x2 - 12x + 9

Or you can use FOIL.

(2x - 3)2 = (2x - 3)(2x - 3) = (2x)2 + (2x)(-3) + (-3)(2x) + (-3)2 = 4x2 - 12x + 9

hope I could be helpful

Choose the correct conic section to fit the equation.

olchik [2.2K]

I believe the correct answer from the choices listed above is option A. The correct conic section that fits the equation above would be a circle. The general form of a circle given the center is at the origin is written as:

x^2 + y^2 = r^2

Hope this answers the question.

What is the equation of the axis of symmetry of this parabola? y=-5(x+4)^2+3

Ede4ka [16]

Answer:

$x=-4$

Step-by-step explanation:

Given the equation of parabola

$y=-5(x+4)^2+3$

This is the vertex form of the parabola equation. Hence, the vertex of the parabola is at point $(-4,3)$

This parabole goes downwards in y-direction (the leading coefficient -5 is negative)

The axis of symmetry of parabola is a vertical line that divides the parabola into two congruent halves. The axis of symmetry always passes through the vertex of the parabola . The x -coordinate of the vertex is the equation of the axis of symmetry of the parabola.

Thus, the equation of the axis of symmetry is

$x=-4$
