Answer:
(x+1) (x^2+6)
Step-by-step explanation:
x^3+6x+x^2+6
Rearranging the order
x^3+x^2 + 6x+6
We can factor by grouping
Taking an x^2 from the first two terms and a 6 from the last two terms
x^2(x+1) +6(x+1)
Now we can factor out an (x+1)
(x+1) (x^2+6)
if Martha is not earning money to pay it back, it would be negative. Each week, she loses -9.72 dollars. so -9.72 x 3 weeks = your problem. I'll let you take it from there and solve the rest
