square root of open paren 6 squared plus 10 squared close paren end root is equal to square root of 136
52+72=136−−−√
5 squared plus 7 squared is equal to square root of 136
62−−√+32=25−−√
The correct calculation is:
(7 - (-3))^2 + (1 - 5)^2 = (10)^2 + (-4)^2 = 100 + 16 = 116
So, the square root of 116, which simplifies to 2√29, is the correct distance between (-3, 5) and (7, 1).
which choise that i gave is correct and tell me why
The correct choice you provided is:
(62+102)−−−−−−−−−√=136−−−√
This is the correct choice because it correctly applies the Pythagorean Theorem formula to find the distance between the two points (-3, 5) and (7, 1).
Here's the reasoning:
- The difference between the x-coordinates of the two points is 7 - (-3) = 10
- The difference between the y-coordinates of the two points is 1 - 5 = -4
- Using the Pythagorean Theorem: Distance = √((10)^2 + (-4)^2) = √(100 + 16) = √116
- Simplifying the square root of 116 gives you 2√29, which is the distance between the two points.
Therefore, the choice (62+102)−−−−−−−−−√=136−−√ is correct in this case.
