Question

What is the value of m ? How do you solve it ?

Answer 1

We have a parallelogram.

The diagonals of a parallelogram bisect each other. This means that each diagonal is divided in two equal segments by the other diagonal.

This let us write:

$9=2n-1$

and

$m+8=3m$

We can solve for n as:

$\begin{gathered} 9=2n-1 \\ 9+1=2n \\ 10=2n \\ n=\frac{10}{2} \\ n=5 \end{gathered}$

and for m as:

$\begin{gathered} m+8=3m \\ m-3m=-8 \\ -2m=-8 \\ m=\frac{-8}{-2} \\ m=4 \end{gathered}$

Answer: the value of m is 4.

Answer 2

value of m is 4 you are correct
