Answer:
Least common denominator is 120.
5/8 = 75/120
-11/15 = -88/120
17/(-24) = -85/120
7/12 = 70/120
75 > 70 > -85 > -88
5/8 > 7/12 > 17/(-24) > -11/15

Answer:
10
Step-by-step explanation:
AB + BC = AC and AC = 14
x + 15 + 2x + 32 = 14 add like terms
3x + 47 = 14 subtract 47 from both sides
3x = -33 divide both sides by 3
x = -11 now the length of BC
2x + 32 replace x with -11
2*(-11) + 32 = 10
The greatest common factor is 7.
