Vasily states that−6(5g−7h+9−10g) can be rewritten as−30g+42h−54
.

Which of these explains whether Vasily is correct?

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

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;

Rearranging the above, we have;

Simplifying, we have;

Multiply, to open the bracket;

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

part 1 answer = 8

part 2 answer = 72

step-by-step explanation:

part 1 explanation = add all of the numbers, then divide by how many numbers you have. so, 200/25 = 8.

part 2 explanation = not gonna lie, this is hard to explain, so just google how to do it.
