3x + 3x + 3x = 3* (3x) = 9x
It is an expression that is equivalent to -3x-19.

3x + 3x + 3x = 3* (3x) = 9x
3x-3y?
It is an expression that is equivalent to -3x-19.
The expression equivalent to 5 plus 3x plus 10 can be simplified by combining the constant terms. Adding 5 and 10 gives 15, so the expression simplifies to 3x + 15. Therefore, the equivalent expression is 3x + 15.
To determine if ( 3x(12 - 2x) ) is equivalent to ( x(12) ), we can simplify the left side. Expanding ( 3x(12 - 2x) ) gives ( 36x - 6x^2 ). The expression ( x(12) ) simplifies to ( 12x ). Since ( 36x - 6x^2 ) is not equal to ( 12x ), the two expressions are not equivalent.

The equivalent expression of 3x-9 plus 3x plus 5 is negative 4.
Radical (3x) = radical(x) * radical(3).
To find an equivalent expression to ( 4 + 3(5 + x) ), first apply the distributive property: ( 3(5 + x) = 15 + 3x ). Then, add this result to 4: ( 4 + 15 + 3x = 19 + 3x ). Thus, an equivalent expression is ( 19 + 3x ).
It is equivalent to 15x+10
To simplify the expression (5X - 6) - (3X + 12), first distribute the negative sign: (5X - 6) - 3X - 12. Then combine like terms: 5X - 3X - 6 - 12, which simplifies to 2X - 18. Thus, the final expression is 2X - 18.
