A) 3x + y - 2z - 9 - 3r + 5s
B) -3x - y - 2z - 9 - 3r + 5s
C) 3x + y + 2z + 5 - 3r + 5s
D) 3x + y - 2z - 5- 3r + 5s
E) -3x - y + 2z + 5 - 3r + 5s

Question

Quizplus · Accepted Answer

Removing the parentheses and distributing the negative signs correctly results in $3x + y - 2z - 7 - 3r + 5s - 2$, which simplifies to $3x + y - 2z - 9 - 3r + 5s$.

Remove the Parentheses from the Expression (3x+y)−(2z+7)−(3r−5s+2)( 3 x + y ) - ( 2 z + 7 ) - ( 3 r - 5 s + 2 )(3x+y)−(2z+7)−(3r−5s+2)
