Let's analyze each statement based on the expression \( 6x^2 - 2x - 14y + 3x \).
-
Before simplifying, there are 4 terms in the expression.
- The expression can be broken down into four parts: \( 6x^2 \), \( -2x \), \( -14y \), and \( 3x \).
- True.
-
6x² and 3x are like terms.
- Like terms are terms that have the same variable raised to the same power. \( 6x^2 \) and \( 3x \) have different powers (\( x^2 \) and \( x^1 \)), so they are not like terms.
- False.
-
The coefficient on y is 14.
- The term \( -14y \) means that the coefficient of \( y \) is \(-14\), not \( 14\).
- False.
-
Simplified, the expression is 6x² + 5x - 14y.
- When simplifying, we combine like terms. The like terms in the expression are \( -2x \) and \( 3x \), which combine to make \( 5x \). Therefore, the expression simplifies to \( 6x^2 + 5x - 14y \).
- True.
-
The commutative property allows the expression to be written as 6x² - 14y + 3x - 2x.
- The commutative property states that the order of addition does not change the sum. The terms \( 6x^2 \), \( -14y \), \( 3x \), and \( -2x \) can indeed be rearranged this way without changing the expression.
- True.
In summary, the truth values for the statements are:
- True
- False
- False
- True
- True
