Answer:
The length between the two points is RT = 1.3 units
Step-by-step explanation:
The coordinates of the point R and T are R(2,1.2) and T(2,2.5).
Now, by DISTANCE FORMULA:
The distance between two coordinates P and Q with coordinate P(a,b) and Q(c,d) is given as:
So, here the distance RT =
or, RT = 1.3 units
Hence, the length between the two points is RT = 1.3 units
2 x -6 equals 0. add 6 to both sides. divide both sides by two. x equals 3
Answer:
18
Step-by-step explanation:
3^4=9*9=81
14-5=9
