I don’t get most of it, but I believe “doubles” means two of the same number added together. For example, 9+9 is a double. I think “doubles +1” means a double and add one. For example, 6+6+1. If I were your sister, I would write “9+9 = 18” for doubles and “6+6+1 = 13” for doubles +1.

I hope I helped!

Answer:

21. D

22. C

Step-by-step explanation:

21. The expansion of the given expression is ...

$\displaystyle -\frac{1}{2}\left(-\frac{3}{2}x+6x+1\right)-3x=\frac{3}{4}x-3x-\frac{1}{2}-3x\\\\=\left(\frac{3}{4}-3-3\right)x-\frac{1}{2}=\boxed{-5\frac{1}{4}x-\frac{1}{2}}$

22. The least likely team to make the championship game is the one with the lowest probability.

3/8 < 1/2 < 2/3 < 4/5

The Bulldogs are least likely to play in the championship game.
