Answer:

8 2/3 units.

Step-by-step explanation:

As bothe the circles and the arcs are congruent, the chords QR and LN are also congruent.

So LN = QR

x + 7 = 4x + 2

7 - 2 = 4x - x

3x = 5

x = 5/3.

Therefore the length of QR = 4x + 2

= 4(5/3) + 2

= 20/3 + 6/3

= 26/3

= 8 2/3 units.

What goes in the space? (3x − ...)2 = 9x2−6x+1 I will give points and brainliest!

Crazy boy [7]

${(x - y)}^{2} = {x}^{2} - 2xy + {y}^{2}$

$(3x - ...)^{2} = 9 {x}^{2} - 6x + 1 \\ {(3x - 1)}^{2} = 9 {x}^{2} -6x + 1$
