I'm guessing this is a parallelogram or something, so VR=TS and RS=VT
therefore, y=x+11 and x+2=y-3x
y=x+11 , 2=y-4x
y=x+11 , y=4x+2
then use the process of elimination:
y=4x+2 then plug in: y=3+11
- y=x+11 y=14
0=3x-9 I think this is how you'd do it, tbh it's just an educated
3x=9 , x=3 guess. Btw, sorry if it looks weird
Finding the rate of the weight gain, we divide the total weight gained with the total number of months that took to gain that weight.
Total time (months) = 0.5 + 2 + 3.5 = 6 months
Total weight (kg) = 80.6 + 88.4 + 96.2 = 265.2 kilograms
Rate = Kg ÷ Months
Rate = 265.2 ÷ 6 = 44.2
44.2 kilograms per month

A square is always a rectangle because it is a quadrilateral with all four angles being right angles ( 90 degrees).
