if A is the midpoint of line segment PR, PA= 7x-11, and PR= 8x+14, then what is the value of line segment AR?
2 answers:
Answer:
PA+AR=PR
AR= PR- PA
AR= 8x+14-(7x-11)
AR= 8x+14-7x+11
AR= x+25
Now, if A is midpoint of PR, then
PA=AR
7x-11= x+25
6x=36
x=6
Put value of x in AR
AR= 6+25= 31
Hope this will help:)
Answer: x+25
Step-by-step explanation:
Here.
PR = 8x+14
& PA = 7x-11
and A is the mid point of PR
so according to condition , PR - PA = AR
⇒ 8x + 14 -(7x -11) =AR
⇒8x +14 -7x + 11 = AR
∴ AR = x+25
