The greatest common factor of 26 and 14 is 2.
So if QR and PQ are the same ( which they are bc the angles and other sides are the same) 3n-1= 5n-7 so -1= 2n -7 so 6 = 2n so n = 3 then QR is 5n -7 so 5 x 3 is 15-7 is 8 so the answer is 8. Hope this helps :)
You have r^2 = 64 and want to find the square root of 64, which we'll call r.
√(r^2) = r = plus or minus √64
or: r = plus or minus 8
