The equation to find the area of a trapezoid is, A=(base1+base2)xHeight/2
1) (5+23)x12/2= 168
2) (1.1+3.4)x2/2= 4.5
3)(17.75+10.25)x8/2= 112
You calculate the number of ways that 2 people can be chosen from 10.
The formula:
n! / r! * (n-r)! =
10! / 2! * 8! =
10 * 9 * 8! / 2 * 8! =
10 * 9 / 2 =

Polygon a figure especially closed figure having three or more sides usually straight side.
So the answer would be equilateral
ANSWER= 14 oz bottle

19.99 - 2 = 17.99 (28oz)
28 is triple the price when it’s only two times bigger
