problem problem just says rectangular dog ben nothing about squar feet so i am assuming so that the dog has the most room

A = 2(4) + 2(8) 8 + 16 = 24 then you would divide the 8 and the 16 by 2 giving the dimensions 4 4 8 8 =24 is this correct

A = l + w the best dimensions would be lenght 10 feet and width 4 feet 24 - 4 = 20 20 divided by 2 (lenght) 10 10 by 10 by 4 = 24

24 divided by 3 (sides) = 8 8 divided by 2 (sides) = 4 24 - 4 = 20 20 divided by 2 (sides) = 10 10 by 10 by 4 = 24 feet of fencing

-0.2x<-12 -0.2/-0.2 to get x alone then -12/-0.2=-60 so x=-60

6/6=1 so there is 6 1/6 in one and 3/6=1/2 so there is 3 1/6 in 1/2

add -3/4 to -3/4 to cancel it out then add -3/4 to -6 so you have 1/4x=-1.5 divide 1/4 by 1/4 to get the x alone then divide -1.5 by 1/4 and whatever that comes out to be equals x
