The perimeter of a train ticket is 72 centimeters. the ticket is 14 centimeters tall. how long is it?

Let the perimeter = base + base + height + height.

Let base = b; height = h; Perimeter = p

Simplify.

p = 2(b) + 2(h)

Perimeter =72, height = 14

72 = 2(b) + 2(14)

Simplify

72 = 2(b) + 28

Isolate the b. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.

Subtract 28 from both sides

72 (-28) = 2b + 28 (-28)

72 - 28 = 2b

44 = 2b

Isolate the b. Divide 2 from both sides

(44)/2 = (2b)/2

b = 44/2

b = 22

22 centimeters is your answer

1: -2 3/4, -2 1/2, -14, 0, 3, 8 1/3

2: -4, -3, -2 1/2, -2 1/4, 3 1/4,

step-by-step explanation:

when rotating a figure 180 degrees, imagine that you are able to take the figure and turn it clockwise or counterclockwise around a center point. to rotate a figure 180 degrees, you will need to apply the rule (x, y) → (-x, -y). start by using a coordinate grid with coordinates for each vertex of the figure. the center point of the coordinate grid is located at (0, 0), which is what you will rotate the figure around. write down the original coordinates of the shape you are going to rotate. then, apply the rule. for example, coordinate (1, 2) becomes (-1, -2). another example would be, coordinate (-4, -2) becoming (4, 2). after you change each original coordinate to the rotated coordinate, you will draw your new figure.
