3a - 2b
-6(a-3b-9c)
6+7a+6b
11a+7b-(3b-2a)
It is: 4b+6
2a
It is: b+4 when simplified
3A + 9B = 3(A + 3B)
0.6b + 3c
3b -1
To simplify the expression 3b^2 - 3b, we first factor out the common factor of 3b. This gives us 3b(b - 1), where b - 1 is the simplified form of the expression. This expression represents the difference between 3 times the square of a variable b and 3 times the variable b.
5b + 11 - 2b = 3b + 11
To simplify the expression ( A + 3B + 5A + 15B ), first combine like terms. The terms involving ( A ) are ( A ) and ( 5A ), which combine to ( 6A ). The terms involving ( B ) are ( 3B ) and ( 15B ), which combine to ( 18B ). Therefore, the simplified expression is ( 6A + 18B ).
