If its 7/4
it would be 1.75
Physical properties are anything that will change how it looks but not how it acts.
for example one could be a phase change. where water turns into steam. which is just water in gas form
another example would be pebbles are just rocks but crushed up.
and another physical change would dents. like if you hit a table and it got a dent. it's still a table just with a dent.
chemical changes change the actual way the chemical works.
the way you can tell is by if it gets heat or has a new property that wants their before.
some examples would be lighting wood on fire. it changes the composition of the wood and now it is no longer flammable.
another one would be burning magnesium. it becomes a new substance when you burn it.
the last example could be photsynthiss. you start with carbon and water and turn it into glucose and oxygen
14x-3x= 11x and the 17 stays the same, so the answer is 11x/17 or answer B.
In a right triangle, the hypotenuse is always the longest side. Plus, the hypotenuse squared has to equal the sum of the squares of the other 2 sides. For the first "triangle" above: does
![14 ^{2} =5 ^{2} +4 ^{2}](https://tex.z-dn.net/?f=14%20%5E%7B2%7D%20%3D5%20%5E%7B2%7D%20%2B4%20%5E%7B2%7D%20)
? Let's check. 196 = 25 + 16 so does 196 = 41? Obviously not. So that is not a right triangle. Let's check the second one the same way. Does
![5 ^{2} =3 ^{2} +4 ^{2}](https://tex.z-dn.net/?f=5%20%5E%7B2%7D%20%3D3%20%5E%7B2%7D%20%2B4%20%5E%7B2%7D%20)
? 25 = 9 + 16. Does 25 = 25? Of course it does! So 1 is not a right triangle, but 2 is!
Do you need only the 2 largest numbers or all of them? (I'll answer in comments)
