1,4(-4x+5)

It looks like you are trying to simplify the expression \( 1.4(-4x + 5) \). Here's how to do that step by step:

1. Distribute \( 1.4 \) to each term inside the parentheses:

\[ 1.4 \cdot (-4x) + 1.4 \cdot 5 \]

2. Calculate each term:

\[ 1.4 \cdot (-4x) = -5.6x \] \[ 1.4 \cdot 5 = 7 \]

3. Combine the results to get the simplified expression:

\[ -5.6x + 7 \]

So, the simplified form of the expression \( 1.4(-4x + 5) \) is:

\[ -5.6x + 7 \]
