Answer:

The sum of all the sides to this quadrilateral will equal a total of 20 inches, so you set up the equation:

2 + 2x + 7 + x + 2 = 20

Solve for x by combining like terms;

(2 + 7 + 2) + (2x + x) = 20

Which simplifies to;

11 + 3x = 20

Get rid of constants;

-11          -11

3x = 9

Isolate x by getting rid of it's coefficient;

/3  /3

<u>x = 3</u>

Now, to find the length of PQ, we plug in the value of x(3) into the equation that contains the line PQ.

x + 2

<u>3</u> + 2

= <u>5 inches.</u>

Now, to find the length of RS, we plug in the value of x(3) into the equation that contains the line RS.

2x

2(3)

= <u>6 inches.</u>
