I would go with A because if u use the distributive property u get something very similar
The first answer is A because (b+6) represents the sidewalk length. (With the pool length and the two corners, which equal 3 ft each.) Then, the sidewalk width would be (h+6) for the same reason. Multiply them and get the pool area plus the sidewalk area. But you only need the sidewalk area so you would subtract the pool area from the whole area, to get (b+6)(h+6)-bh, or A in the end.
Unfortunately, I do not know the answers to the rest of the problems. I still hope this helped though!

Hello!
To understand this question we first need to find some common measurements to make this math easier.
One day is equal to 24 hours.
One hour is equal 60 minutes.
One day in hours would be equal to 24 · 60, or 1440 minutes.
1440 is equal to 100% of our day.
To find 50% we can then divide that value in half to get 720 minutes.
Half of that value, or 25%, is equal to 360 minutes.
