UNO [17]

Considering the perimeter concept, we have that:

  • Danielle's mistake is that she did not consider two outside edges, one of length 6x - 4 and the other of length 12x + 3.
  • The correct perimeter, in feet, is: P = 50x + 27.

<h3>What is the perimeter of a polygon?</h3>

The perimeter of a polygon is given by the sum of all the lengths of the outside edges of the polygon.

For this problem, the outside edges are given as follows:

  • 2 of 6x - 4, due to the isosceles triangle.
  • 2 of 12x + 3, due to the rectangle.
  • 1 of 14x + 13, also due to the rectangle, and only one, because of the other part of the rectangle with the same length is internal to the prism;

Danielle's mistake is that she did not consider two outside edges, one of length 6x - 4 and the other of length 12x + 3. Considering all the edges, the perimeter is given by:

P = 2(6x - 4) + 2(12x + 3) + 14x + 13

P = 12x - 8 + 24x + 6 + 14x + 13

P = 12x + 24x + 14x + 8 + 6 + 13

P = 50x + 27.

See attachment ^ Need help with graphing problem :)​
Blizzard [7]

Answer:

x=-4, multiplicity = 2

x=-1, multiplicity = 3

x=5, multiplicity = 4

Step-by-step explanation:

The graph bounces off the x-axis at x=-2 and x=5, so the multiplicity has to be an even number. The only even number is 2 and 4.

The graph crosses the x-axis at x=-3, so the multiplicity has to be odd, and th oenly odd number is 3.
