Answer:
15.62 units.
Step-by-step explanation:
To commence with, find for the vector.
Points = (7,-5) and (2,-5)
7 + 2
-5 + -5
12
-10
Vector = 12
-10
Magnitude = y² + x²
Points = (12,-10)
-10² + 12²
100 + 144
244
Square root of 244 is 15.62
Therefore, the distance between the points is 15.62 units.
Hope it helps.
35 because 11 times 2 equals 22 and plus 13 equals 35
