To move from scientific notation to standard from move the decimal point the number of places of the exponent on the 10. In this case the exponent is -11, so you will need to move 11 places to the left. You will get:0.0000000000556 in standard form.
Answer:

Step-by-step explanation:
To solve this one we will subtract how much he spends from what he has. At the start he had 19 and then spent 8 meaning he now has 8 less than when we started so 19-8 is 11. He now as 11 dollars, then he spend another 4 meaning we have to subtract another 4 dollars. 11-4 is 7. So he as 7 dollars left at the end.
I hope this helps and please don't hesitate to ask if there is anything still unclear!
X^2=x+12
minus x+12 both sides
x^2-x-12=0
factor
(x-3)(x+4)=0
set each to zero
x-3=0
x=3
x+4=0
x=-4
x=3 or -4
answer is first one
