This was the question, right: \[2m^2-4n^2+3m-6m^2-2m+7n^2\] That simplifies \[=2m^2-6m^2+3m-2m+7n^2-4n^2\]\[=-4m^2+m+3n^2\] Which is the answer a not c.

Answer 32

You have the growth of each child. And you want the growth of them both together. So you need to add the individuals growths. \[5x-1+2x+3=?\]

Answer 33

9x

Answer 34

5x−1+2x+3=9x

Answer 35

\[5x+2x=7x\]\[-1+3=2\] So \[5x+2x-1+3=?\]

Answer 36

5x+2x-1+3=9x

Answer 37

No, it is \[5x+2x-1+3=7x+2\] You cannot add the +2 into the x's, they are not the same

Answer 38

Just like you cant say 7 apples + 2 bananas = 9 apples

First calculate the sum of Thomas's expression, just like we did with the last question. And then calculate Kellys expression. Now you subtract them from each other and find the difference.

Answer 43

So we start with Thomas's expressions: \[3x+7+2x-3=?\]

Answer 44

3x+7

Answer 45

Yes that is the first expression he took from the bag. The second is 2x - 3. So add those together

Answer 46

add 3x+7 to 2x - 3

Yes, what is that?

Answer 48

\[3x+7+2x-3=?\]

Answer 49

9x

Answer 50

You can imagine the x's as apples and the other numbers as bananas.
