Answer:
distance=63.95
Step-by-step explanation:
distance formula is: distance²=(x₂-x₁)²+(y₂-y₁)²
So, you would just plug everything in! I would look like this: (66-3)²+(-6-5)²
Then, you would simplify: (63)²+(-11)²
Simplify again: 3969+121=4090
Then, since you must remove the square on the distance, you must do it on both sides. I would look like this: 
= 
And the answer is: distance=63.95
Answer:
The middle two expressions shown are not polynomials
Step-by-step explanation:
Polynomial terms have positive integer exponents on any variables. A 2/3 power is not an integer exponent. Division by y is equivalent to an exponent of -1, which is not a positive integer.
Answer:
Step-by-step explanation:
= -1
Answer:
parallelogram
Step-by-step explanation:
technically its a quadrilateral too but seeing as it has 2 sets of parallel lines Im going with parallelogram.
The answer is B : the square root of 25 is 5, because 5x5=25.
So it's 18-5....
Hope I helped :)
