11. Maya's family is building a deck. The deck has
6 sides. Each side of the deck is 12 feet long
What is the perimeter of the deck?

72 feet

Step-by-step explanation:

This is an example of a regular hexagon. A hexagon is  a polygon that has 6 sides. It is regular because all the sides are equal.

Perimeter of a Regular Hexagon=6l

Length of one side, l=12 feet

Therefore:

Perimeter of the deck = 6 X 12 =72 feet

if the eqn of the parabola is f(x) = (x-4)(x+2), we need to mult. this out to find the coordinates of the vertex.

then f(x) = x^2 + 2x - 4x - 8, and f(x) = x^2 - 2x - 8.

one way in which you can find the vertex is to calculate x = -b / (2a).   here, that comes to

        )

x = = 1.   f(1) = 1^2 - 2(1) - 8 = - 9.   vertex is at (1, -9).

        2(1) 

find another point on the curve:   let x=0, for which y=-8.   then (0, -8) is on the curve.   plot the vertex and this point and draw a smooth parabola thru both.

hope this
