Hello!!
Circumference of a circle = 2πr
and

Answer:
-9
Step-by-step explanation:
Replace x with -7 in the expression:
x^2 + 5 / x + 1
-7^2 + 5 / -7 + 1
49 + 5 / -6
54/-6
simplify the fraction
9/-1 = -9
 
        
             
        
        
        
Answer:
7
Step-by-step explanation:
Since, M is between S and T. 
Therefore, SM + MT = ST
9x- 8 + 2x + 3 = 72
11x - 5 = 72
11x = 72 + 5
11x = 77
x = 77/11
x = 7
