Answer:

3

Step-by-step explanation:

The diagonals of a parallelogram are congruent.  This means that WC = 2x+5 = CY = 3x+2:

2x+5 = 3x+2

Subtract 2x from each side:

2x+5-2x = 3x+2-2x

5 = x+2

Subtract 3 from each side:

5-2 = x+2-2

3 = x

The diagonals of a parallelogram bisect each other.
Therefore WC = CY.
That is,
2x + 5 = 3x + 2
Subtract 2x from each side.
5 = 3x - 2x + 2
5 = x + 2
Subtract  from each side.
5 - 2 = x + 2 - 2
3 = x

Answer:  x = 3

Hope this helps!

Why is (-3,6] a better answer than (-3,6)
Pani-rosa [81]

(-3, 6) includes all numbers between -3 and 6 but it does not include -3 and 6.

when you put square parentheses you include the number on the edge

so if an anwser includes all numbers between -3 and 6 and the number 6 it's correct to write (-3,6]
