Zero because -12 does not equal 12
27x² and 81x⁵
81 = 27*3
x⁵ = x²x³
81x⁵ = 27*3*x²x³= (27x²)*3x³
We can see that 81x⁵=(27x²)*3x³ includes as a factor 27x²,
so GCF is 27x².
Answer:
The Pythagorean Theorem is used for right triangles only, because it's a mathematical relation between the legs of the triangle and the hypothenuse, where each leg must be less than the length of the hypothenuse.
It's important to correctly identify each element of the triangle, that is, which sides are legs, and which side is the hypothenuse, because the Pythagorean Theorem has a specific order, that means, if we make a mistake identifying each element, then the result will be wrong.
For example, the expression
is the theorem, where
is the hypothenuse. This theorem states that the square of the hypothenuse (longest side) is equal to the sum of the square of the legs. So, if we call
a leg instead of the hypothenuse, the theorem won't work.
Obtuse and isosceles
Isosceles means that at least two of the sides are congruent or equal.
Obtuse means that one angle of the triangle is greater than 90 degrees.
So, your answer is D and E
