Question

Vasily states that−6(5g−7h+9−10g)

Answer 1

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;

$-6 (5g - 7h + 9 - 10g)$

Rearranging the above, we have;

$-6 (5g - 10g - 7h + 9)$

Simplifying, we have;

$-6 (-5g - 7h + 9)$

Multiply, to open the bracket;

$30g + 42h - 54$

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