Answer:

A. Vasily is not correct. He should have rewritten the original expression as −6(−5g−7h+9) and then as 30g+42h−54.

Step-by-step explanation:

Given the expression;

[tex] -6 (5g - 7h + 9 - 10g)[/tex]

Rearranging the above, we have;

[tex] -6 (5g - 10g - 7h + 9)[/tex]

Simplifying, we have;

[tex] -6 (-5g - 7h + 9)[/tex]

Multiply, to open the bracket;

[tex] 30g + 42h - 54[/tex]

Therefore, Vasily should have rewritten the original expression as −6(−5g−7h+9) and then as 30g+42h−54.
