Answer:
QRP
Q = 8x-10
R = 7x+6
P = 7x+8
Step-by-step explanation:
Let x be any positive integer, say x=2
P=7x+8=(7*2)+8=22 units
Q=8x-10=(8*2)-10=6 units
R=7x+6=(7*2)+6=20 units
From the above, Q is the shortest and P is the longest side. Therefore, the sides arranged from shortest to longest will be Q, R, P
4x+2=5x-6
4x-5x=-6-2
-x=-8
therefore, x=8
4cm = 5km
5/4 = 1.25
1cm = 1.25km
5 × 1.25 = 6.25
<em>6.25km</em>
Hope this helps! :)
