I believe the answer is A. 20, 30, 40 is NOT a pythagorean triple.
Answer:
well you just get 32
Step-by-step explanation:
but i divide 16 divide 5 and got 3.2 so it might be an extra .2 stickers
I can prove by being smart then that if you tell me all the ansers
2x^2 + 8x - 12 = 0..divide by 2
x^2 + 4x - 6 = 0
x^2 + 4x = 6...add 4 to both sides of the equation
x^2 + 4x + 4 = 6 + 4
(x + 2)^2 = 10....<== ur constant is 10
x + 2 = (+-)sqrt 10
x = -2 (+ - ) sqrt 10
x = -2 + sqrt 10
x = -2 - sqrt 10
