It is 6a + 4
4a+3a-4 = 10 4a+3a = 10+4 7a = 14 a = 2
(5a+8) - (2a+4) =3a +4 To do this, simply subtract like terms. 5a-2a=3a and 8-4=4
= a + b - 2
When simplified it is: 2a+8b+4
It is 6a + 4
2a + 3a + 4 = 5a + 4
(3a - 4)(3a - 4)
It can be simplified to: 3a^2 +10a+7 or factored as (3a+7)(a+1)
4a + 3a = (4 + 3)a = 7a
7a
3a plus 4 equals 3a +4. You can not combine the two parts because they are not like terms so there is no way to simplify this.
4a+3a-4 = 10 4a+3a = 10+4 7a = 14 a = 2
a = 3a + 4 0 = 2a + 4 2a = -4 a = -2
3a + a = 4a Example: a = 5 (3x5) + 5 = 15 + 5 = 20 = 4 x 5
a is equal to 4
(2a - 3)(3a - 4)
