75x−338.2
75 x minus 338 point 2

−69.19x+38.2
negative 69 point 1 9 x plus 38 point 2

−72.2x+41.21

Answer 1

To simplify the expression \(-9.2(8x - 4) + 0.7(2 + 6.3x)\), we can start by distributing the values outside of the parentheses:

1. Distributing \(-9.2\):
\[
-9.2(8x) + -9.2(-4) = -73.6x + 36.8
\]

2. Distributing \(0.7\):
\[
0.7(2) + 0.7(6.3x) = 1.4 + 4.41x
\]

Now we combine the two results:

\[
-73.6x + 36.8 + 1.4 + 4.41x
\]

Next, combine like terms:

- For the \(x\) terms:
\[
-73.6x + 4.41x = -69.19x
\]

- For the constant terms:
\[
36.8 + 1.4 = 38.2
\]

Putting it all together, the simplified expression is:

\[
-69.19x + 38.2
\]

Thus, the correct response is:
\(-69.19x + 38.2\)
