In this problem, we're given a parallelogram.
00:07
Our parallelogram has vertices of mn, p, q, and it has diagonals qn and mp.
00:23
And they connect at point r here.
00:26
We're given that qr, this section here, is 2x plus 3, and then r in, this section here is x plus 7.
00:38
We want to find the values of qr.
00:43
Rn, and qn.
00:49
So for a parallelogram, we know that the diagonals bisect each other, so that means that an r is going to be equal to rq, so we can set those two values equal to each other to find x.
01:03
So x plus 7 equals 2x plus 3, can subtract x from both sides.
01:11
7 equals x plus 3.
01:16
We're going to subtract 3 from both sides.
01:22
And x equals 4...
