7*4=28
7-4=3
so the width is 4 feet and the length is 7 feet
21) 3(2j-k)=108 It is asking you to set the equation equal to j
distribute the 3
6j-3k=108
move k to the other side by adding on both sides
6j=108+3k
divide everything by 6
j=18+0.5k
I think it is the first one -2
I would say that it is 81. I hoped this helped and the steps are first what is 16 divided by 2 is 9 then you do 9 times 9 witch is 81.
D. because 9:45 and 12:60 because if you divide y by x it’s 5, while 3:12 and 6:24 are 4
