2(3x + 4) = 6x + 8 3(x - 5) = 3x - 15 6x + 8 - 3x + 15 = 3x + 23
2(3x + 4) = 6x + 8 3(x - 5) = 3x - 15 6x + 8 - 3x + 15 = 3x + 23
3x + 8
2(3x + 4) = 6x + 8 3(x - 5) = 3x - 15 6x + 8 - 3x + 15 = 3x + 23
It is: 2x2 + 25/3x - 35/9 remainder -46/9
It is an expression that can be simplified to 4x
To simplify the expression (9x + 4y - 6x - 5y), combine like terms. For the (x) terms, (9x - 6x = 3x), and for the (y) terms, (4y - 5y = -1y) or (-y). Therefore, the simplified expression is (3x - y).
To simplify the expression ( 3x(6x - 7) + 6 ), first distribute ( 3x ) to both terms inside the parentheses: [ 3x \cdot 6x - 3x \cdot 7 = 18x^2 - 21x. ] Then, add the constant ( 6 ): [ 18x^2 - 21x + 6. ] So, the simplified expression is ( 18x^2 - 21x + 6 ).
The last one is an example of like terms.
