Step-by-step explanation:

Cool thanks bro I appreciate it
9 and 12 have a common factor of 3 so 9/12 = 3/4
The distance formula is given by:

We are given two points A and B as
A(1,1) and
B(7,-7)
so we have ,
x1 = 1 , y1=1
x2= 7 and y2=-7
Plugging these in the formula we have:

d=√(36+64)
d=√100
d=10
Answer: The distance between A(1,1) and B(7,-7) is 10
Answer:
-5f+6
Step-by-step explanation:
-4f-f = -5f
15-9= 6
Answer is -5f+6
Hope this helps!
