Parallelogram LMNO has two diagonal lines, LN and MO, that intersect at P. The length of LP can be expressed by 3x - 4, and PN by the expression X + 14. identify a pattern regarding the diagonals of the parallelogram to find the value of x

1 answer

In a parallelogram, the diagonals bisect each other. This means that the segments formed by the intersection point of the diagonals (in this case, point P) are equal in length.

Since \( P \) is the midpoint of diagonals \( LN \) and \( MO \), we can express this relationship mathematically using the lengths given:

\[ LP = PN \]

According to the problem, we have:

\[ LP = 3x - 4 \] \[ PN = x + 14 \]

Setting these two expressions equal to each other, we get:

\[ 3x - 4 = x + 14 \]

Now, solve for \( x \):

  1. Subtract \( x \) from both sides:

\[ 3x - x - 4 = 14 \] \[ 2x - 4 = 14 \]

  1. Add 4 to both sides:

\[ 2x = 18 \]

  1. Divide both sides by 2:

\[ x = 9 \]

Thus, the value of \( x \) is \( 9 \).
