12a2b + 6a = 6a(2ab + 1)
12a- 6a + a = 7a Since they all have the same variable, you can simply add and subtract 12-6 = 6 6+1 = 7
4a+8a = 12a 12a divided by 2 = 6a
It is 20a - 5b - 9.
Well, let's take a moment to appreciate the beauty of these numbers dancing together on the canvas of mathematics. To find out what 12a equals, we can combine like terms by adding 4a and 2a to get 6a, and adding 6b and 4b to get 10b. So, 12a equals 6a plus 6a, which simplifies to 12a. Just like adding happy little trees to a painting, math can be a joyful experience when we take it step by step.
21a - 6a
12a²
12a
12a^2
6a
It is not clear whether the question is 3a + 4a + 5a + 6a^3 which would be 12a + 6a^3 or 3a + 4a + 5a + (6a)^3 = 12a + 216a^3 or (3a + 4a + 5a + 6a)^3 = 5832*a^3 But none of these really require summation notation!
