Simplify the expression: 4(2x - 3) - 5(x + 2)
Responses

a) 3x - 13 
a) 3x - 13 

b) 3x + 13 
b) 3x + 13 

c) 8x - 16  
c) 8x - 16  

d) 6x - 11 
d) 6x - 11 

Let's simplify the given expression step by step:

The expression is:

\[
4(2x - 3) - 5(x + 2)
\]

1. First, distribute the constants:
   - Distribute \(4\) to \(2x - 3\):
     \[
     4(2x) = 8x \quad \text{and} \quad 4(-3) = -12
     \]
     So, \(4(2x - 3) = 8x - 12\).

   - Distribute \(-5\) to \(x + 2\):
     \[
     -5(x) = -5x \quad \text{and} \quad -5(2) = -10
     \]
     So, \(-5(x + 2) = -5x - 10\).

2. Now, combine the two parts:
   \[
   8x - 12 - 5x - 10
   \]

3. Combine like terms:
   \[
   (8x - 5x) = 3x \quad \text{and} \quad (-12 - 10) = -22
   \]

Thus, the simplified expression is:
\[
3x - 22
\]

None of the provided options match exactly, but based on the work done, it seems there may be a mistake in the answer choices. The correct simplified expression is:

**\(3x - 22\)**.
