Which of the following would likely form a
heterogeneous mixture?
sand and water
salt and water
O baking soda and water
sugar and water

Sand and water. The other mixtures would be homogeneous since they will eventually dissolve into the water and form a solution. Sand won’t distribute evenly, settling at the bottom and can still be filtered out/separated.

It would be 15 m how i got the answer: (20x20) + b^2 = (25x25)400 + b^2 = 625625-400=225square that and get 15hope this : )
