2a+5a+9a = 16a
The simplified expression is -9a -9b.
There is nothing you can do to 9a + 5 without knowing the value of a.
9a + 3b - 11a - 4b = -2a -b
-14 + 9a = 389a = 52a = 52/9 or 5.78
12a + 6b + 9a + 14b =(12a + 9a) + (6b + 14b) =21a + 20b
(9a + 2)(9a + 2)
2a+5a+9a = 16a
a2+9a+20 = (a+4)(a+5) when factored
9a + 7b *remember to look and understand the letters!*
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.
That cannot be simplified any further so it is: 9a + 45z
9a + 3b - 11a - 4b = -2a -b
-14 + 9a = 389a = 52a = 52/9 or 5.78
2 + 3A + 9A = 2 + 12AThe numerical value depends on the value of 'A'.It changes whenever 'A' changes.
