Step-by-step explanation:
sqrt(x^2+81)=x+10
x^2+81=x^2+20x+100 (which is one of the options)
81=20x+100
-19=20x
x=-19/20
So there's the work done.
Answer:
so Carson's problem was at the end, since the neighbors are paying 10$ PER DAY, and 3 days work would only earn him 30$ meaning at the end he would be a dollar short, technically, he needs to work exactly 3.2 days, or...
let's say he works 4 hrs a day
1 Day = 4Hr
3.2 Days = X
X = 3.2 × 4
= 12.8 Hrs
so Carson needs to work 3 days and an extra 48 Minutes
16= 6 ones or 16 ones
817= 8 hundreds and 7 ones or 17 ones
Hope this helps! :D
