Find the value of x for which ABCD must be a parallelogram

2 answers:

6 0

Parallelograms have opposite sides that are equal, so you can set BC and AD equal to each other to find the value of x if the figure is a parallelogram.
x + 3 = 2x - 1
3 = x - 1
4 = x

Now check
4 + 3 = 2(4) - 1
7 = 7

The value of x that makes ABCD a parallelogram is x = 4.

Hope this helps =)

Answer:The Collatz conjecture is a conjecture in mathematics that concerns a sequence defined as follows: start with any positive integer n. Then each term is obtained from the previous term as follows: if the previous term is even, the next term is one half the previous term. If the previous term is odd, the next term is 3 times the previous term plus 1.
