Answer:
180 meters
Step-by-step explanation:
You first need to find the length of each line:
PQ= 75 meters
PR= 60 meters
RQ= 45 meters
You then add all of the sides together.
75 + 60 + 45 = 180
I was gonna answer but I’m not sure and I don’t want u to get it wrong so I’m just not gonna tell u sorry
we need to get y alone so subtract 2x from both sides of the equation
2x+4y=12
-2x -2x
-----------------------
4y=-2x+12 now divide both sides by 4
y = -2x/4 +12/4
y = -1/2 x +3
