Answer:

2.73     8.75

Step-by-step explanation:

n = 1  

1 (DOUBLE) = 1+1 = 2  

2 +3/4 = 1.5

1.5 +2 = 3.5  

3.5 x 0.22 = 0.77

3.5 - 0.77 = 2.73

n = 1

1 + 3/4 = 1 + 0.75 = 1.75

1.75 (DOUBLE) = 3.5

3.5 x 2 1/2 = 8.75

svetoff [14.1K]
Yes, they will equal each other because the question says that the line is the perpendicular bisector of JK.
So,
25x-18=13x+90
12x=108
x=9
Now to find the length of JK, do 25(9)-18+13(9)+90
The answer is 414.
