Answer:
Two sets of vertical angles are formed.
Well, that's incorrect because according to the Order of Operation [GEMS\BOMDAS\PEMDAS etc.], that -7 has to be distributed amongst all the other terms in parentheses. Besides, you did the wrong operation when you inserted that subtraction symbol in substitution of the parentheses, which means to MULTIPLY. So, the order goes as follows:
12 - 7[72]
-504 + 12 = -492 [OR 12 - 504]
-492 is your answer. You get it now?

THE ANSWER
let be S1 = <span>Serravalle
S2= </span><span>San Marino and
S3= </span><span>Chiesanuova
for finding the distance </span><span>Chiesanuova from Serravalle,
(distance S1 to S2) + (distance S2 to S3) = </span><span>982 miles + 833 miles =1.815 miles
the answer is </span>B. 1, 815 miles
