Find the area of the trapezoid shown. a. 39 square root 3 sq units b. 43.5 sq units c. 43.5 square root 3 sq units

43.5√3 sq. units

Step-by-step explanation:

Base 1 of trapezoid is 10.

Base 2 of trapezoid is 16 + 3 = 19

The height = 3√3 (To get the height you had to multiply the number 3 from the bottom base of the trapezoid by the square root of three)

Now plug these numbers into the trapezoid formula: A = 1/2(3√3)(10 + 19)

Simplify to get: 43.5√3 sq. units

Hope this helps you understand! P.S. I helped someone else out on this problem, so I just copied and pasted my answer from the previous question onto here. :) So, it's still my own work.

(n^3 - n)

= n(n-1)(n+1)

since it is divisible by 3 and 2 ,because it is a multiple 3 consecutive number

if, n-1 is odd then n+1 is also odd, then it is a multiple of 9

but if, n-1 is even then n+1 is also even, then it is a multiple of 4

so, largest multiple = max(9*2, 4*3) = max(18, 12) = 18

7 is the median   7.875 is the mean
