Well to figure out if your answer is right, plug in -5, -1, and 0 where they need to be, and do the equation to see if it equals with the answer in the problem.

Answer 8

Okay, thank you :)

Answer 9

So what is

-5 + 5*-1 - 4*0 = -10

2*-5 - -1 + 5*0 = -9

2*-5 - 10*-1 - 5*0 = 0

Answer 10

Um.. im not sure.. :/

Answer 11

First multiply..

-5 + \(\color{magenta}{5*-1}\) - \(\color{magenta}{4*0}\) = -10

\(\color{magenta}{2*-5}\) - -1 + \(\color{magenta}{5*0}\) = -9

\(\color{magenta}{2*-5}\) - \(\color{magenta}{10*-1}\) - \(\color{magenta}{5*0}\) = 0

Answer 12
