How can you represent 2⋅−15 with a model?(1 point) Responses 15+15 15 plus 15 −(−15+−15) negative left parenthesis negative 15 plus negative 15 right parenthesis −(15+15) negative left parenthesis 15 plus 15 right parenthesis −15+−15

Answer 1

To represent \( 2 \cdot -15 \) with a model, we can interpret the expression as "2 times -15", which can be thought of as adding -15 two times. This can be represented as:

\[ -15 + -15 \]

This matches the response provided.

Thus, the correct response is: \[ -(-15 + -15) \] (or more simply, \(-15 + -15\))

This indicates the sum of two negative values, consistent with the multiplication of 2 and -15.
