A rectangle has a length that is 12 inches shorter than 3 times its width. If the perimeter is 144 inches, what are the dimensions?
W+W+L+L= 2W + 6W-24=144
Wow thank you so much that really helped me!!
no problem, any questions you got, ill be here for ya
I am just a little confused by this subject, such as where you got the 6W at the very top
one length equals 3w-12, so just double that 2(3w-12)=6w-24
