Creo que es la C no estoy muy segura
Answer:
I would say A
Step-by-step explanation:
To me it is C. or D. but you would need a second opinion. Sorry.
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". ☺☺☺☺
