3y/5 3y+4 whats the length of a retangle

Therefore AC = BD

=> 3y/5 = 3y - 4

=> 3y = 5(3y - 4)

=> 3y = 15y - 20

=> 12y = 20

=> y = 20/12 = 5/3

Therefore AC = 3y/5

= 3(5/3)/5

= 1 units

and BD = 3y - 4

= 3(5/3) - 4

= 5 - 4

= 1 units

the answer is

The length of each diagonal is 1 units

start with a line segment pq that we will copy. mark a point r that will be one endpoint of the new line segment. set the compasses' point on the point p of the line segment to be copied. adjust the compasses' width to the point q. the compasses' width is now equal to the length of the line segment pq.

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.
