Hello! And thank you for your question!

First we are going to expand the equation:

−2m^2−2mn+8m−10m+10n+nm+4n^2−5n

Then we are going to combine like terms:

−2m^2+(−2mn+mn)+(8m−10m)+(10n−5n)+4n^2

Then finally, simplify:

−2m^2−mn−2m+5n+4n^2

Final Answer:

−2m^2−mn−2m+5n+4n^2

Which of the systems of equations below is equivalent to the system shown?

amm1812

Answer:

$D.....is\: the \: equivalent \: system$

Step-by-step explanation:

$if \to 4x + 5y = 3 \\ if \to 2x + 3y = 1 \\then \\ 2 \times \: 4x + 5y = 3 \\ 4 \times 2x + 3y = 1 \\ 10y - 12y = 6 - 4 \\ - 2y = 2 \\ \boxed{ y = - 1} \\ 4x + 5y = 3 \\ 4x +5( - 1) = 3 \\ 4x - 5 = 3 \\ 4x = 3 + 5 \\ 4x = 8 \\ \boxed{x = 2} \\ hence \: the \: equivalent \: system \: is \to D \\$

Cedric's basketball team scored fewer than 76 points in their last game. Which of the following inequalities represents the numb

Lelechka [254]

Answer: $n$

Step-by-step explanation:

Although you did not provide the inequalities, the only inequality that can represent the number of points Cedric's basketball team scored in their last game is the one shown below:

Let's call the number of points Cedric's basketball team scored in their last game: $n$ .

You know that Cedric's basketball team scored fewer than 76 points in their last game. "Fewer than" means "less than", which is represented with the symbol < .

Therefore, you can represent the number of points Cedric's basketball team scored in their last game with the following inequality:

$n$
