The simplified expression is -9a -9b.
It is not an equation but an algebraic expression that can be simplified to: 12b-5a
(12a+9b)(12a-9b)
The expression (6a + 9b + 15) contains three terms. Each term is separated by a plus sign: (6a), (9b), and (15). Thus, the total number of terms is three.
There are 3 terms in the given expression of 6a+9b+15
The simplified expression is -9a -9b.
9b-13b= -4b -4b = 40 Divide both sides by -4 b = -10
It is not an equation but an algebraic expression that can be simplified to: 12b-5a
What I would do is change the problem up. Instead of b-9b I would make it -(9b-b). It is still the same problem; you will multiply the number inside the parenthesis be -1. So start with 9b-b. That would equal 8b. So it would change from -(9b-b) to -(8b) so you multiply 8b by negative 1 (-1) to get the answer -8b. -8b is your answer. So b - 9b = -8b
3a + 5b - 6a - 9b = -3a - 4b
If you mean: (3b+7)^2 then it is 9b^2+42b+49
(12a+9b)(12a-9b)
If you mean: 7b+b+b then it is 9b simplified
-2ab
15b+2-13 = 13b+6-4b 15b-11 = 9b+6 15b-9b = 6+11 6b = 17 b =17/6 or 2 and 5/6
The expression (6a + 9b + 15) contains three terms. Each term is separated by a plus sign: (6a), (9b), and (15). Thus, the total number of terms is three.
