Answer:-2=-2
Step-by-step explanation: i took the assignment
Suppose the three sides are a, b, and c, with c being the longest, a being the shortest
first equation: c=(a+b)-66
second equation: 2a=c-55=> c=2a+55
plug c=2a+55 into the first equation: 2a+55= a+b-66 => b=a+121
a+b+c=a+(a+121)+(2a+55)=7272 =>4a+176=7272 =>a=1774
a=1774, b=1895, c=3603
Answer:
8
Step-by-step explanation:
first simplify exponent
2^3 = 8
so you have
4 + 8 - (2 + 2)
then just add and subtract to get
12 - 4 = 8
