Answer:
17
125
Step-by-step explanation:
exterior angle is equal to sum of interior opposite angle. so
( 2x + 6 ) + ( 5x ) = ( 8x - 11 )
7x + 6 = 8x - 11
x = 17
exterior angle = ( 8 * 17 ) - 11 = 125
We can see the sequence goes by decreasing 9 on each number
so the numbers are
2, -7, -16, -25, -34, -43, -52, -61, -70
so adding all these numbers we get
2-7-16-25-34-43-52-61-70
= -306
hope this helped

Answer:
B
Step-by-step explanation:
Initial mean = 156, Changed mean = 163.92
So, mean increases. Only condition that satisfies this is B.
Answer:
C=x (x+3)
Step-by-step explanation:
x cannot divide x+3 definitely so the denominators must be multiplied to get the least common denominator.
