You divide 7 by 7 and 56 by 7, 56 divided by 7 is 8, therefore the unit rate is $8 per book.
Altitude = 90* Angle
15^2+b^2 = 39^2
225+b^2 = 1521
1296 = b^2
36= b
15^2 + b^2 = 17^2
225 +b^2 = 289
64 = b^2
8 = b
36 + 8 = 44
39+17 = 56
56 is greater then 44
Triangle Inequality Theorem Proves
So QR = 44
