9a +8 -2a -3 -5a = 2a +5
It is the same as: 9a -4a = 5a
It is: 9a-a-a = 7a
If: 9a = 18b Then: a = 2b
The simplified expression is -9a -9b.
There is nothing you can do to 9a + 5 without knowing the value of a.
32AA is Smaller then 32A.
It is the same as: 9a -4a = 5a
It is: 9a-a-a = 7a
9a-99 = -90
9a - 8a = a
If: 9a = 18b Then: a = 2b
9a verbal expression
9a squared = 81a^2
30b and 32a are the same size for the cups but different bands 30b has a tighter band than 32a
Yes. 32A is bigger and 32AA is smaller
9a+21 3(3a+7)
The simplified expression is -9a -9b.
