Answer: x = ± 11+√113 ;
______
2
Step-by-step explanation:
x^2=11-2
Add two to both sides
x^2+2=11x-2+2
Simplify
x^2+2=11x
Subtract 11x from both sides
x^2+2-11x=11x-11x
Simplify
x^2-11x+2=0

Answer: You cannot buy it.
Step-by-step explanation:
$450 with a 20% percent discount would be $360
Add in a sales tax of 5.25%, and it amounts to $549 in total.

Answer:
60km
Step-by-step explanation:
There are two ways to look at this
1. Finding the unit rate
We can find how many km he travels in 1 hour by diving both the hours and km by 2. 1 hour = 10km so 6 hours is 60km since we multiply by 6.
2. Multiply by 3
We can multiply both the km and hours by 3, since 2x3=6 hours
20km * 3 hours = 60km
