9a + 7b *remember to look and understand the letters!*
3a^2 + 3a^2 = 6a^2 3a^2 - 3a^2 = 0 3a^2 x 3a^2 = 9a^4 3a^2 divided by 3a^2 = 1
The given expression can be simplified to: 3b-a
Ah, let's take a moment to appreciate the beauty of algebra. To factorise 6ab - 9ac, we can first factor out the greatest common factor, which is 3a. This leaves us with 3a(2b - 3c), where 2b - 3c is the factored expression. Just like painting a happy little tree, we've simplified our expression with a few gentle brushstrokes.
81(a^4)

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.
9a + 7b *remember to look and understand the letters!*

The variable.In algebra a can represent a number - any number, it does not have to have a value like 6 or 31¼ until you have worked one out.You could say, what is a if 3a + 6 = 24? Mathematicians like that kind of problem but if you learn how to solve it, it is a powerful thing that you can use for different problems.3a + 6 = 24 can also be written as 3a = 18, so a = 6 is the solution. It is also the solution to the question: what is the number that if you triple it and add 6, the answer is 24? by doing the algebra, you get the answer 6 quite quickly, but the good thing about algebra is that it gives a framework for solving much more difficult questions as well, that you can't do in your head.
3a + 2b is an expression in algebra. If you make 3a + 2b equal to something then you can find the values of "a" and "b" Lets say you make 3a + 2b equal to 23 3a + 2b = 23 Now find "a" and "b" to make this equation true... 3(5) + 2(4) = 23 15 + 8 = 23 23 = 23 Correct So in this case a=5 and b=4
Oh, dude, it's like math time! So, when you add 3a and 7a together, you get 10a. It's like combining the apples and oranges of algebra. So, the simplified answer is just 10a. Easy peasy, lemon squeezy!
Your equation would look like this: .3a = 22.05 After that, it's just a matter of algebra: $73.50
3a^2 + 3a^2 = 6a^2 3a^2 - 3a^2 = 0 3a^2 x 3a^2 = 9a^4 3a^2 divided by 3a^2 = 1
7a minus 2, if "3a-2" means 3a minus 2. 3a plus 1 and 1-3rd in parenthesis times 3a, if "3a-2" means 3a squared. a plus 3a squared plus 3a = 1-3rd times 3a plus 3a times 3a plus 1 times 3a = 3a plus 1 and 1-3rd in parenthesis times 3a
If you mean: 4a +29 -3a -a +3a then it simplifies to 29 +3a
You divide numbers by numbers, you don't divide letters. If you are talking about algebra - where letters stand for numbers - then the answer would depend on the value of the letter a. "a" multiplied by any integer is divisible by a, for example: 0a = 0, 1a = a, 2a, 3a, 4a, 5a, -a, -2a, -3a, etc.
