Answer:
(C)
Step-by-step explanation:
In order to find whether the given side lengths form a right triangle or not, we must show that it satisfies the Pythagoras theorem.
A. , 10 and 116
According to Pythagoras theorem,
⇒
⇒
which does not satisfy the condition, therefore these side lengths do not form a right triangle.
B. 3,6 and 8
According to Pythagoras theorem,
⇒
⇒
⇒
which does not satisfy the condition, therefore these side lengths do not form a right triangle.
C. 30, 40 and 50
According to Pythagoras theorem,
⇒
⇒
⇒
which satisfies the condition, therefore theses side lengths form right triangle.
Answer:
Answer A in your list
Step-by-step explanation:

If , then:
which is the first answer in your list of possible options
Answer:
The correct answer is 6.
Step-by-step explanation:
2x2 – 2x + 10 <------ This is the original expression.
2x2 – 2(4) + 10 <----- Change the variable.
4 - 2(4) + 10 <------- Do the multiplication to the left.
4 - 8 + 10 = <------ Do the multiplication in the middle.
-4 + 10 = <----- Do the subtraction to the left.
6 <----- Simplify
Hope this helps! :D
Answer: do you have a calculator, if you dont just look it up -.-
Step-by-step explanation: (sorry if this sounds rude, im not trying to be)
No because the perfect trinomial has a square as the third term and the middle term is a multiple of 2.
