Answer:
number of members in 2006=190
230members on 2010
Step-by-step explanation:
2008-2006=2
20*2+150= 190 ans (1)
b)
20x+150=230
20x=230-150= 80
x= 80/20=4---ans (2)
Well 120 is 1/3 of the square so the 9ft is 2/3 of the square so it is B

The result of this computation is a number that begins 2.56.... Since the hundredths digit is more than 4, the tenths digit is rounded to the next higher value, from 5 to 6.
Rounded to tenths, 2.1√1.488 = 2.6
