Ah, what a happy little question we have here! When you multiply 3a by 2a, you simply multiply the numbers together and then multiply the variables together. So, 3 times 2 is 6, and a times a is a^2. Therefore, 3a x 2a equals 6a^2. Just remember, there are no mistakes, only happy little accidents in math!
3a x 2a =24
3a-2a = 1
3a + (3b - 2a) + 5b =3a + 3b - 2a + 5b =(3a - 2a) + (3b + 5b) =a + 8b
3a + 2a = 5a
since a=1a, 3a-1a=2a
Simplifying a = 3a + 12 Reorder the terms: a = 12 + 3a Solving a = 12 + 3a Solving for variable 'a'. Move all terms containing a to the left, all other terms to the right. Add '-3a' to each side of the equation. a + -3a = 12 + 3a + -3a Combine like terms: a + -3a = -2a -2a = 12 + 3a + -3a Combine like terms: 3a + -3a = 0 -2a = 12 + 0 -2a = 12 Divide each side by '-2'. a = -6 Simplifying a = -6
2a2 x 3a-3 = (2 x 3)a(2 + -3) = 6a-1
depends what the value of 'a' is.
5a + 4b - 3a =(5a - 3a) + 4b =2a + 4b =2 (a + 2b)
2a + 5a + 3a = 10a
a + a + a - 2a = 3a - 2a = a
2a - 5a = -3a
