Answer:
B. No.
Step-by-step explanation:
We have been given 3 side lengths 7 ft, 12 ft, 17 ft. We are asked to determine, whether the given set of lengths can form a right triangle or not.
We will use Pythagoras theorem to solve our given problem, which states that the square of hypotenuse of a right triangle is equal to the sum of squares of two legs of right triangle.



Since the sum of squares of both legs is less than square of hypotenuse, therefore, the given set of lengths can not be the side lengths of a right triangle.
It’s probably true as matter is either gas liquid or solid

Answer: 
Step-by-step explanation:
You can do long division, which is very very hard to show with typing on a keyboard. You essentially want to divide the leading coefficient for each term. Ill try my best to explain it.
Do
. Write 2x^2 down. Now multiply (x - 3) by it. Then subtract it from the trinomial.

Now do
. Write that down next to your 2x^2. Multiply 3x by (x - 3) to get:

Your final step is to do
. Write this -2 next to your other two parts
Multiply -2 by (x - 3) to get:

Our remainder is 0 so that means (x - 3) goes into that trinomial exactly:
times
