<h3>Answer: 72</h3>
========================================
Explanation:
If W is the first letter, then we have 4 ways to select the other letters. The order matters so we use a permutation. Use either the nPr formula or the factorial notatation.
nPr = 4P4 = (4!)/(4-4)! = 24/1 = 24
or simply 4! = 4*3*2*1 = 24
We have 24 ways to pick the four other letters after W is chosen.
This logic applies if H is the first letter or if T is the first letter. Imagine 3 rows of 24 different cells per row. Each row represents the first letter (W, H or T). In total, we have 3*24 = 72 cells overall.
You can write the complete steps as 3*4! = 3*24 = 72.
Answer:
56x-38
Step-by-step explanation:
2(8x+9)-8(7-5x)
16x+18
-8(7-5x)
-56+40x
16x+18-56+40x
Add all like terms
