Answer:
A 20 sqrt(2)
Step-by-step explanation:
4 sqrt(50) + 4 sqrt(12) - 2 sqrt(27) minus 2 sqrt(3)
We know that sqrt(a) sqrt(b) = sqrt(ab)
this is the first expression
4 sqrt(25)sqrt(2) + 4 sqrt(4)sqrt(3) - 2 sqrt(9)sqrt(3)
4*5sqrt(2) + 4*2 sqrt(3) - 2*3 sqrt(3)
20 sqrt(2) +8 sqrt(3)-6sqrt(3)
20 sqrt(2) +2 sqrt(3)
Now we subtract 2 sqrt(3) from the above expression
20 sqrt(2) +2 sqrt(3) - 2 sqrt(3)
20 sqrt(2)
A Pythagorean triple is a triple that describes the three positive integer side lengths of a right triangle. It fits the rule a^2 + b^2 = c^2. From the given sets of numbers above, the following are the Pythagorean triples: Option C: 12, 16 and 20 (144 + 256 = 400); Option E: 8, 15 and 17 (64 + 225 = 289); and Option F 32, 60 and 68 (1,024 + 3600 = 4,624).
Answer:
5. D (4,6)
6. B (7.8)
Step-by-step explanation:
5. Add the two X coordinates (6+2) and divide that by 2 (8/2=4), do the same for the two Y coordinates (4+8=12, 12/2=6)
