Answer:
B. obtuse
Can't be right because 100 would have to = ab^2 + ac^2
to be acute, ab^2 + ac^2 would have to be greater than 100
35 square units is the answer
Suppose that the polynomial x^2+y^2-1 is not irreducible.
It means that there exists two fractions such that :

We found that q divide t and q divide s, but s and t are supposed to be prime each other. It is a contradiction.
The polynomial x^2+y^2-1 is then irreducible in q[x,y]
Answer:
to get the circumference 3.14×14=43.96
radious is doubled because it is half the diameter
