Answer:
20 units
Step-by-step explanation:
Since they lie on the same horizontal line,
There's only horizontal distance:
11 - (-9) = 20 units
Answer:
d= 20
Step-by-step explanation:
1. Equation for finding length segment:
d= √ (x1 - x2)2 + (y1 - y2)2
2. Find the values
Let (x1, y1) = (11,10)
Let (x2, y2) = (-9, 10)
3. Substitute
d= √ (11- -9)2 + (10 - 10)2
d= √ (20)2 + (0)2
d= √ (400) + (0)
d= √ (400)
d= 20
Hope this helped :)
