To determine the expressions that are equivalent to \( 4(x+3)-10+6x \), we should first simplify the given expression step-by-step:
1. Distribute the \( 4 \) inside the parentheses:
\[
4(x+3) = 4x + 12
\]
2. Substitute this back into the expression:
\[
4x + 12 - 10 + 6x
\]
3. Combine like terms:
- Combine \( 4x \) and \( 6x \):
\[
4x + 6x = 10x
\]
- Combine \( 12 \) and \( -10 \):
\[
12 - 10 = 2
\]
4. Putting it together, we have:
\[
10x + 2
\]
Now, we will evaluate each of the provided expressions to find those that are equivalent to \( 10x + 2 \):
1. **\( 10x - 7 \)**: Not equivalent, since \( 10x + 2 \neq 10x - 7 \).
2. **\( -2x - 7 \)**: Not equivalent, as it does not match \( 10x + 2 \).
3. **\( 2(5x + 1) \)**:
\[
2(5x + 1) = 10x + 2
\]
Equivalent.
4. **\( 2(8x + 1) \)**:
\[
2(8x + 1) = 16x + 2
\]
Not equivalent.
5. **\( 4x + 3 - 10 + 6x \)**:
\[
4x + 3 - 10 + 6x = 10x - 7
\]
Not equivalent.
6. **\( 4x + 12 - 10 + 6x \)**:
\[
4x + 12 - 10 + 6x = 10x + 2
\]
Equivalent.
Based on these calculations, the expressions that are equivalent to \( 4(x+3)-10+6x \) are:
- \( 2(5x + 1) \)
- \( 4x + 12 - 10 + 6x \)
Thus, the correct responses are:
- \( 2(5x + 1) \)
- \( 4x + 12 - 10 + 6x \)
