Final answer:
The expression p - 10p + 4p can be simplified by combining the like terms. The equivalent expression is -p.
Step-by-step explanation:
The expression p - 10p + 4p can be simplified by combining the like terms. Like terms have the same variable raised to the same power. In this case, all the terms have the variable p raised to the power 1.
So, p - 10p + 4p is equal to -5p + 4p which simplifies to -p.
Therefore, the expression that is equivalent to p - 10p + 4p is -p.
