I don't know if I'm right Y=10
Answer:

Step-by-step explanation:
Let the outside temperature be
degree.
So, when
degree, number of members, 
Now, for every degree rise in temperature, 10 members gets added.
So, when the temperature is
degrees, rise in temperature is
degrees.
Therefore,
For
degrees rise, number of members added = 
Hence, total number of members added as a function of temperature is given as the sum of members at
degrees and for
degrees rise. This gives,

Answer:
Step-by-step explanation
Note that if x>2, then x+3>3+2=5. Then x+3>0. Recall that the absolute value function is defined as


Since x+3>0, we have that |x+3|=x+3
Step-by-step explanation:
EQUATION: Volume=length x width x height.
V=l×w×h
1620cm^3=9cm×9cm×xcm
1620cm^3=81cm^2 ×xcm
xcm= 1620cm^3/81cm^2
xcm= 20cm
