Answer:
8 hours.
Step-by-step explanation:
60x8=480
Hope this helps!
First square both sides
1-3x=(x+3)^2 use foil to unfactor it
1-3x=x^2+6x+9 subtract 1 from both sides
-3x=x^2+6x+8 add 3x to both sides
0=x^2+9x+8
Now that we got it equal to zero you have to factor the new trinomial
0=(x+1)(x+8)
Now since both are being multiplied by each other, if you get 1 of them to equal zero then both equal zero since 0 times anything equals 0.
So your solutions are x=-8 and x=-1
