Answer:
5765865876+5737555586=11503421462
25 unit
Step-by-step explanation:
from the diagram
QS=QR+RS
26=(2x-39)+(x+5)
26=3x-34
3x=34+26
3x=60
x=60/3
x=20
now
RS=x+5
RS=20+5
RS=25 unit
The answer to the question is b
K= -240
2/6k + 80 = 3/6k +120
2/6k -2/6k + 80 = 3/6k-2/6k +120
80 = 1/6k + 120
80 -120 = 1/6k +120 -120
-40 = 1/6k
-40 / 1/6 = 1/6k / 1/6
k = -240
