5a+95 :D
3a squared plus nine = 19a. 3a to the second power = 9a plus 9 = 19a.
3a + 9 =3X(a + 3)
13a - 6 + a = 5a + 3 + 3a 13a + a - 5a - 3a = 3 + 6 6a = 9 6a/6 = 9/6 a = 3/2
11a-3a =8a so 8a+9=-7 8a = -16 a=-2
a2 - 6a + 9 = a2 - 3a - 3a + 9 = a(a - 3) - 3(a - 3) = (a - 3)*(a - 3) = (a - 3)2
a = 15.

A = 3B = 5 ___________ 2 ( 3A + B) = 2 (9 + 5) = 2 (14) = 28
it could be anything. What is a? if it is 3 then you do 4x3=12+3x3=9+3=24 * * * * * It is 8a.

The 'answer' is the number that 'a' must be in order to make the statement true. In order for 9 to equal 3a, 'a' must be 3 .
