Are the expressions -0.5(3x + 5) and -1.5x + 2.5 equivalent? Explain why or why not.

Respuesta :

No, they are not equivalent because if you distribute the -0.5 in the expression -0.5(3x+5) you will get -1.5x-2.5 which is not the same as -1.5+2.5

Answer:

Step-by-step explanation:

Expanding the first statement using the distributive property yields -1.5x - 2.5. The two formulations are not equal because the constant term does not have the same sign as the second expression. Furthermore, if you replace x with a value and evaluate each equation, the results will not be equal.
