Let l and l-6 be the length and width, respectively, of the rectangle. Then:
l(l-6)=40
l²-6l-40=0
(l-10)(l+4)=0
l=10,-4
The rectangle is 10" by 4". ☺☺☺☺
Answer:
B. 3 pages are edited every five minutes
D. 6/10 of a page is edited per minute
Step by step:
Three pages are done at an interval of five minutes.
Six tenths of a page is done every minute
