8a+4a=144 12a=144 12a/12=144/12 A=144
5x - 8a + 4a - 2x + a = 3x - 3a
48a3 + 32a2 + 4a = 4a(12a2 + 8a + 1)
A = 4
(48a3+32a2+16a)/4a = 12a2+8a+4
8a + 5g
Add the equations: 4a + 4a - 5b + 5b = 7 + 17 ie 8a = 24 a = 3, so b = 1
4a+8a = 12a 12a divided by 2 = 6a
6a-3=8a+11 -3-11=8a-6a -14=2a a=-7
They are: 1, 2, 4, 8, a, 2a, 4a and 8a.
Add 8a to each side: -6a + 14 = 2 Subtract 14 from each side: -6a = -12 Divide each side by -6: a = 2. Job done.
20a plus 14 will be 34a minus 8a minus 7 34a minus 8 is 26a minus 7 is 19a. The single b is 1b plus 6b which is 7b minus 2b equals 5b.
it could be anything. What is a? if it is 3 then you do 4x3=12+3x3=9+3=24 * * * * * It is 8a.
−4a + 139 = 4a + 123 → −8a = −16 → a = 24a + 123 → 4(2) + 123 = 8 + 123 = 131°
The GCF is 4a^2
11a-3a =8a so 8a+9=-7 8a = -16 a=-2
8a = 12 so a = 1.5
3a 4a 5a 6a 7a 8a
8a times (2 + 1)
7x - 8a = 3x + 24a First, add 8a to both sides: 7x = 3x + 24a + 8a Now subtract 3x from both sides to get all x terms on one side: 7x - 3x = 24a + 8a Simplify... 4x = 32a And divide both sides by 4: x = 32a / 4 = 8a x = 8a
a^2 + 8a + 15
a = 3 !
