Lasandra wants to center a towel bar on her door that is 29 inches wide she determines that the distance from each end of the towel bar to the end of the door is 7.75 inches write and solve an equation to find the length of the towel bar

13.5 inches

Step-by-step explanation:

Let x be the length of the towel bar.

Since, the towel bar's ends from each end of the door are 7.75 each,

Thus, the width of the door = x + 7.75 + 7.75 = x + 15.5

But, According to the question,

The width of the door = 29 inches,

Therefore, x + 15.5 = 29

⇒ x = 13.5 inches

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.
