a + 7b + 2c
4b plus 7b plus 5 will equal 11b plus 5. When you have two variables that are the same you can add the two numbers with the variables remaining the same.
6a + (7b - 4a - 8b) = (6a - 4a) + (7b - 8b) = 2a - b
100a2 - 49b2 is the difference of two perfect squares. Therefore, it is equal to the sum times the difference of the roots: (10a + 7b)(10a - 7b)
If b = 5, 7b = 35
2B Multiplied by 3 plus B = 7B. Here is how it's worked out. You start with 2B, multiply that by 3 and you get 6B. Now all you have to do is add the last B, therefore adding 1B to equal 7B.
No. 7b - 2b = 5b
What is the answer of (3a+7b) (3a-7b)?
If you mean: -3*(-2b-3)+7b then it is an algebraic expression that can be simplified to 6b+9+7b = 13b+9
It is: 7b+10 simplified
(-3b - 4)(-2b + 5)
10a+7b undefined variables cannot be determined
-7a-7b
It is an equation and the value of b is 3
The given expression can be simplified to: 3b-a
a + 7b + 2c
