Question

To find the length of JK you’d set up and solve:

Answer 1

According to the statement, to find x, it is necessary to use the following expression:

`7x=3x+14`

This expression is set up thanks to the definition of a parallelogram. To solve it isolate x to one of the sides of the equation.

`\begin{gathered} 7x=3x+14 \\ 7x-3x=14 \\ 4x=14 \\ x=(14)/(4) \\ x=3.5 \end{gathered}`

x has a value of 14/4 or 3.5.

According to the figure JK measures 7 times x. Use this information to find JK:

`\begin{gathered} JK=7x \\ JK=7(3.5) \\ JK=24.5 \end{gathered}`

JK measures 24.5.
