Answer 6

To simplify \( 4x + 8x \), you can combine the like terms:

\[
4x + 8x = (4 + 8)x = 12x
\]

So the correct answer is:

**12x**

Answer 7

To simplify \( 9g - 7h - 6g + 2h \), we can combine like terms:

1. Combine the \( g \) terms: \( 9g - 6g = 3g \)
2. Combine the \( h \) terms: \( -7h + 2h = -5h \)

Putting it all together, we have:

\[
3g - 5h
\]

So the correct answer is:

**3g − 5h**

Answer 8

To simplify \( 2a - 4b + 7 + 8a + 6b - 2 \), we can combine like terms:

1. Combine the \( a \) terms:
\[
2a + 8a = 10a
\]

2. Combine the \( b \) terms:
\[
-4b + 6b = 2b
\]

3. Combine the constant terms:
\[
7 - 2 = 5
\]

Putting it all together, we get:

\[
10a + 2b + 5
\]

So the correct answer is:

**10a + 2b + 5**

Answer 9

To simplify \( \frac{3}{7}x + \frac{2}{7}x \), you can combine the like terms:

\[
\frac{3}{7}x + \frac{2}{7}x = \left( \frac{3 + 2}{7} \right)x = \frac{5}{7}x
\]

So the correct answer is:

**\(\frac{5}{7}x\)**

Answer 10

The simplified expression is \( \frac{5}{7}x \) (which means \( \frac{5}{7} \) multiplied by \( x \)).

It is not an exponent; \( x \) does not have an exponent of 2 in this case. So the correct option is:

**\(\frac{5}{7}x\)** (not \( x^2 \)).

Answer 11

To simplify \( 67c - 59d - 12c + 13d \), we can combine like terms:

1. Combine the \( c \) terms:
\[
67c - 12c = 55c
\]

2. Combine the \( d \) terms:
\[
-59d + 13d = -46d
\]

Putting it all together, we get:
\[
55c - 46d
\]

None of the provided options exactly match this, but the closest option, based on common mathematical notation for fractions, is:

**None of the provided options are correct.** The correct simplified expression is \( 55c - 46d \).
