Answer:
=3–√−13–√+1⋅3–√−13–√−1
=(3–√−1)23–√2−12
=3–√2+12−23–√3−1
=4−23–√2
2−13–√
a=2,b=−1.

Step-by-step explanation:
Round $17.46 to the Nearest Dollar
This is how to round 17.46 dollars to the nearest dollar.
First, note that $17.46 is the same as 17 dollars and 46 cents.
To round $17.46 to the nearest dollar, means to round $17.46 to a full dollar amount with no cents.
The rounding rule for dollars is as follows: If it is 50 or more cents, you add to the dollar amount. Otherwise, you simply delete the cents.
In $17.46, 46 cents is less than 50, so you simply delete the cents.
$17.46 rounded to the nearest dollar is therefore:
$17

Answer:
6
Step-by-step explanation:
You can memorize these for the smaller shapes
for equilateral polygons:
triangle: 60
square: 90
pentagon: 108
hexagon: 120
Otherwise, I believe the formula is the total degrees in a polygon (s-2)*180 where s is the number of sides.
So the measure of each angle on average would be (s-2)*180/s.
There (s-2)*180/s = 120
180(s-2) = 120s
180s-360 = 120s
60s = 360
s = 6
