A triangle has sides of lengths 12, 14, and 19. Is it a right triangle? Explain.

a. yes; 12^2 + 14^2* ≠ 19^2
b. no; 12^2 + 14^2 = 19^2
c. no; 12^2+ 14^2 ≠ 19^2
d. yes; 12^2 + 14^2 = 19^2

Find the pattern and use it to list the nth term in the sequence. 6, 12, 20, 30, 42, 56, the nth term of the sequence is

Offering 30 if a plus b plus c equals 68 and ab plus bc plus ca equals 1121, where a, b, and c are all prime numbers, find the value of abc. the answer is 1978 but i need an explanation on how to get that.
