Answer: 10
Imagine you have 2 slots or boxes that are empty. They represent the possible choices for the letter you pick. For example, you can place B in slot 1 and D in slot 2. There are 5 choices for slot 1 (A,B,C,D,E) and four choices for slot 2. Why 4? Because after we pick the letter for slot 1, we have one less letter to pick from. We can't reuse that letter.
Now multiply those values 5 and 4 to get 20. There are 20 different ways to pick a pair of letters from a pool of 5 total. However, order does NOT matter because the segment AB is the same as BA. Since order doesn't matter, we are doubly counting when we shouldn't. In other words, our count is two times higher than it should be. Instead of 20 pairs, it's actually 20/2 = 10 pairs. That's why the answer is 10.
The list of 10 segments are: {AB,AC,AD,AE,BC,BD,BE,CD,CE,DE}
Side note: you can use the nCr combination formula with n = 5 and r = 2 to get the same answer.
Here, Just substitute their values,
4x + 3y
= 4(3) + 3(6)
= 12 + 18
= 30
In short, Your Answer would be 30
Hope this helps!
Step-by-step explanation:
If you want to know how to find the area of a trapezoid, just follow these steps.
Identify the length of both bases. The bases are the two parallel sides of the trapezoid. Let’s call them sides A and B. Suppose A is 8 in long and side B is 13 in long.
Add the lengths of the bases. Add 8 in and 13 in. 8 in + 13 in = 21 in.
Identify the elevation of this trapezoid. The height of the trapezoid is vertical to the bases. In this case, assume the elevation of the trapezoid is 7 in.
Multiply the amount of the lengths of the bases by the elevation. The amount of the lengths of these foundations is 21 in and the height is 7 in.
Divide the result by 2. Split 147 in2 by 2 to find the last answer. 147 in2/2 = 73.5 in2. The area of the trapezoid is 73.5 in2.
