P=2(l+w)
Substitute width plus 3 for length
Remember order of operations: multiply before adding
86=2((w+3) + w)
86=2w+6+2w
86=4w+6
80=4w
20=w
23=w+3=l
Check the answer
86=2((w+3) + w)
86=2((20+3)+20
86=2(23+20)
86=46+40
86=86

Another simple way is to just multiply
and 

Should be B.
as x represents the week number you simply plug in 8 for X so,
y=-1.2(8)+23.5
y=13.9 that is just 14 then
