8a+4a=144 12a=144 12a/12=144/12 A=144
(48a3+32a2+16a)/4a = 12a2+8a+4
Add the equations: 4a + 4a - 5b + 5b = 7 + 17 ie 8a = 24 a = 3, so b = 1
it could be anything. What is a? if it is 3 then you do 4x3=12+3x3=9+3=24 * * * * * It is 8a.
5x - 8a + 4a - 2x + a = 3x - 3a
They are: 1, 2, 4, 8, a, 2a, 4a and 8a.

8a+4a=144 12a=144 12a/12=144/12 A=144
12a2-8a-2 2(6a2-4a-1)
48a3 + 32a2 + 4a = 4a(12a2 + 8a + 1)
−4a + 139 = 4a + 123 → −8a = −16 → a = 24a + 123 → 4(2) + 123 = 8 + 123 = 131°
(48a3+32a2+16a)/4a = 12a2+8a+4
The GCF is 4a^2
8a + 5g
It is an equation in the single unknown variable, a. a = -4
Add the equations: 4a + 4a - 5b + 5b = 7 + 17 ie 8a = 24 a = 3, so b = 1
