Expand the following expression.

5.6(23 - 3.17x)
A.
17.752 + 128.8x
B.
28.6 - 8.77x
C.
128.8x - 17.752
D.
128.8 - 17.752x

Answer 1

For this case we have that by definition, the distributive property establishes that:

$a (b + c) = ab + ac$

We have the following expression:

$5.6 (23-3.17x)$

We apply distributive property to the terms within parentheses:

$5.6 * 23-5.6 * 3.17x =\\128.8-17.752x$

Finally, the expression is equivalent to:

$128.8-17.752x$

Answer:

$128.8-17.752x$

Option D
