    x^2+2x+4 can be written as
    x^2 + x(2) + 4*1^2
    I think that the best choice would be
    1 big square, 1 tall rectangle, 4 little squares

    #2
    –3f^2 + 4f – 3 + 8f^2 + 7f + 1
    just collect terms of the same power
    (-3+8)f^2 + (4+7)f + (-3+1)
    5f^2 + 11f - 2

    #3
    (2x^2 + 6x + 1) + (–7x^2 + 2x – 3)
    (2-7)x^2 + (6+2)x + (1-3)
    -5x^2 + 8x - 2

    #4
    (3x^2 – 7x – 4) – (6x^2 – 6x + 1)
    (3-6)x^2 + (-7+6)x + (-4-1)
    -3x^2 - x - 5

    #5 just add up the sides
    2x+3x+4x+1+4x+1
    13x+2

    #6
    (5x^2 – 7x – 6)-(8x^2 + 6x – 1)
    (5-8)x^2 + (-7-6)x + (-6+1)
    -3x^2 - 13x - 5

    #7 ok
    #8 ok

    #9 the number must be less than 10, so instead of 10*10^7 you want 1 * 10^8.

  28. Hey guys! Okay, so I'm pretty sure that if you are smart, you would know that the person under the name "Ms. Sue" isn't Ms. Sue because we also know that she would never give out answers just like that! Plus, there isn't an emoji beside her name soooooo..... but anyway, the real question is: Should we care? I'll let it go through your brain for a bit...

    Time's up!

    The correct answer is "No.". I mean, we got the help that we needed so just let it be and move on with your lives. I'm pretty sure that you aren't depressed enough to talk about if the "Ms. Sue" is real or not. That's all for today folks!

  31. @Some Random Girl, I love reading your responses. You are amazing! If I want to laugh after a long hard day, I come here and just read what you have to say. You are witty, and I love that you are yourself even if it's on a screen. You don't care what people think of you. Sounds like me... Maybe you should hang out with my brother. Maybe he'll get your attitude. Seriously, he lets everyone walk all over him, it ticks me off. Anyway, your cool.
