QuestionFind expressions equivalent to $2(-2 j+7)$. Options include: $-4 j+7$, $2(-4 j+2 j+7)$, $-4 j+14$, $14 j-4$.

Studdy Solution
Now, we compare this simplified expression with the given options. The expressions equivalent to $-4j +14$ are the correct answers.
The first option is $-4 j+7$, which is not equivalent to $-4j +14$.
The second option is $2(-4 j+2 j+7)$, which simplifies to $-4j +14$, so it is equivalent.
The third option is $-4 j+14$, which is exactly the same as our simplified expression, so it is equivalent.
The fourth option is $14 j-4$, which is not equivalent to $-4j +14$.
So, the expressions equivalent to $2(-2 j+7)$ are $2(-4 j+2 j+7)$ and $-4 j+14$.
