when you say 3x, you mean that there are 3 x's. Multiplication implies repeated addition, so three x's added is x+x+x, which equals 3x.
It is a quadratic expression and can be factored into: (3x+1)(x+2)

3x + 5 + x + 10 + 2y 4x + 2y + 15 |:2 2x + y + 7.5 2x + y + 7.5 is equivalent to the original.
what is equivalent to (x plus 4)2
3x2 + 5x + 2 is a quadratic expression that can be factored as follows: 3x2 + 5x + 2 = 3x2 + 3x + 2x + 2 = 3x(x + 1) + 2(x + 1) = (3x + 2)(x + 1)
The expression "negative x plus 3x" can be simplified by combining like terms. Negative x can be written as -1x, so the expression becomes -1x + 3x. When you combine -1x and 3x, you get 2x. Therefore, the simplified expression is 2x.
Radical (3x) = radical(x) * radical(3).
The expression 3x + 5x - 8 is equivalent to 8x - 8 but, since it is not an equation (nor inequality) it cannot be solved. Consequently, x + 1 cannot be evaluated.
When x = 2, 3x + 5 = 11.
It is a quadratic expression and can be factored into: (3x+1)(x+2)
This expression could be reordered as 1 + 3x + 2x2.

Equivalent to what? "3x = 3 + x" is an equation which can be equivalent to other equations, but none is mentioned.
3x+5=14 3x=9 x=3
It depends on what it is meant to be equivalent to!
