Factor the quadratic expression in the equation y = 2x2 + 8x - 154 and find the zeros of the equation. Then use the zeros to find the line of symmetry of the parabola represented by the equation.

What is the equation for the line of symmetry of the parabola represented by the equation
y = 262 + 8x - 154?

Enter your answer as the correct equation like this: x = 42

zeros: -11 , 7

Line of symmetry: x = -2

Step-by-step explanation:

y = 2x² + 8x - 154 = 2*(x² + 4x - 77) = 2*(x+11)(x-7)

y = 0

x = - 11 or x = 7

line of symmetry: x = 1/2 (-11 + 7) = -2

2x² + 8x - 154 = 2*(x² + 4x +4) - 162 = 2 * (x+2)² - 162

vertex (h , k): h = -2 , k = -162

Line of symmetry: x = -2

b is 38 degrees.

a is 52 degrees.

this is because if b is 38 and a is 14 degrees more than b than 38+14=52 and 52+38=90 degrees. hope this .

the volume is the product of the area of the base, 3x(3x+4), and the height, 3x-1
