Hey there! I'm happy to help!
Here's how to find the distance between any two points.
Find the difference of the x values.
-5-7=-12
Square it.
-12²=144
Find the difference of the y values.
6-3=3
Square that.
3²=9
Add the two numbers we got.
144+9=153
√153≈ 12.37.
Have a wonderful day! :D
Answer:
5. 10 cm
6. 12 in
7. 5 mi
8. 13 cm
Step-by-step explanation:
5. 6² + 8² = x²
36 + 64 = x
36 + 64 = 100
√100 = 10
6. 15² - 9² = x²
225 - 81 = 144
√144 = 12
7. 3² + 4² = x²
9 + 16 = x
9 + 16 = 25
√25 = 5
8. 12² + 5² = x²
144 + 25 = x
144 + 25 = 169
√169 = 13
