Circles m and k are congruent, qr is congrent to ln. find the length of qr

Given QR is congrent to LN and QR = 4x + 2 and LN = x + 7.

So, QR = LN

Hence, we can set up an equation as following:

4x + 2 = x + 7

4x + 2 - x = x + 7 - x Subtract x from each sides.

3x + 2 = 7 By simplifying.

3x + 2 - 2 = 7 - 2 Subtract 2 from each sides.

3x = 5

Divide each sides by 3 to isolate x.

So,

Next step is to plug in in QR = 4x+2 to get length of QR.

So,

Since 2 can be written as 2/1.

By multiplying the second fraction by the common denominator 3.

By simplifying the second fraction.
