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.
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
9a+21 3(3a+7)
The simplified expression is -9a -9b.
There is nothing you can do to 9a + 5 without knowing the value of a.
The expression "9a plus 1" can be written mathematically as (9a + 1). This represents a linear equation where (a) is a variable. The value of the expression depends on the value of (a). For example, if (a = 2), then (9a + 1) equals (19).
12a + 6b + 9a + 14b =(12a + 9a) + (6b + 14b) =21a + 20b
