To apply the Distributive Property of Multiplication over Addition correctly for simplifying the expression \( 23 - 9(2x + 5) + 11x \), you would first multiply each term inside the parentheses by -9 (since the expression is -9 times the quantity (2x + 5)).
Distributing the -9 across the terms inside the parentheses gives us:
-9 * 2x = -18x
-9 * 5 = -45
Now, rewrite the expression with the distributed terms:
\( 23 - 9(2x + 5) + 11x \)
\( = 23 - (18x + 45) + 11x \)
\( = 23 - 18x - 45 + 11x \)
Now combine like terms:
\( = 23 - 45 - 18x + 11x \)
\( = -22 - 7x \) (since 23 - 45 = -22, and -18x + 11x = -7x)
There is no option exactly matching the correctly simplified expression (-22 - 7x), but the closest one, which follows the proper application of the distributive property, is:
23 minus 18 x minus 45 plus 11 x
Hence, the correct choice based on the distributive property and assuming a slight error in the final simplification would be:
23−18x−45+11x
23 minus 18 x minus 45 plus 11 x
