10x³
3x² + 7x
7x² + 7x
3x² — x
-2x² + 7x
Which expression is equivalent to
— 3 ( 2x+5) + 7?
—5x —8
— 6x + 12
—2x + 12
—6x—8
-6x + 2
To simplify the expression 5x² + 3x - 2x² + 4x, you can combine the like terms.
First, let's combine the terms that have the same degree of the variable x:
5x² - 2x² = 3x²
3x + 4x = 7x
Therefore, the simplified expression is 3x² + 7x, which is equivalent to the original expression 5x² + 3x - 2x² + 4x.
To simplify the given expression, we need to combine like terms.
The given expression is:
5x² + 3x - 2x² + 4x
Let's first combine the terms with x²:
5x² - 2x² = 3x²
Now, let's combine the terms with x:
3x + 4x = 7x
Therefore, the simplified equivalent expression is:
3x² + 7x
So, the correct answer is: 3x² + 7x.
