Please answer the question correctly. I don't understand.
Which sets of side lengths represent Pythagorean triples? Check all that apply.
A. 1, 2, 5
B. 6, 8, 14
C. 8, 15, 17
D. 10, 24, 26
E. 15, 20, 30
F. 28, 45, 53

Some primitive triples are ...  (3, 4, 5)  (5, 12, 13)  (7, 24, 25)  (9, 40, 41)One interesting characteristic of these is that the sum of the last two numbers is the square of the first number.Any multiple of these will be a Pythagorean triple.Now consider your list.  a) (10, 24, 26) = 2×(5, 12, 13) . . . IS a Pythagorean Triple  b) 2×(7, 24, 25) = (14, 48, 50), so (14, 48, 49) is NOT a Pythagorean Triple  c) 3×(3, 4, 5) = (9, 12, 15), so (9, 12, 16) is NOT a Pythagorean Triple  d) (9, 40, 41) . . . IS a Pythagorean Triple  e) 5×(3, 4, 5) = (15, 20, 25) . . . IS a Pythagorean Triple The sets of side lengths that are Pythagorean Triples are ...  (10, 24, 26)  (9, 40, 41)  (15, 20, 25)

c. 1,233 miles

( - 4 , -7 )

all the lines must parallel  

step-by-step explanation:

coordinates of c = ( - 1 , 2 )

3 units left = ( -4 , 2 )

9 units down = ( - 4 , 11 )
