in rectangle klmn km=7x+20 and ln=55. what is the value of x

Sagot :

Start by drawing the rectangle and naming the corners and distributing the corresponding distances

Since we are talking about a rectangle sides KM and LN are the same, which gives the following equation

[tex]7x+20=55[/tex]

solve the equation for x

[tex]\begin{gathered} 7x=55-20 \\ 7x=35 \\ x=\frac{35}{7} \\ x=5 \end{gathered}[/tex]

The value of x is 5.
