Answer:
235989936000
Step-by-step explanation:
To form 8 letter words from 30 letters
Using permutation :
nPr = n! ÷ (n-r)!
30P8 = 30! ÷ (30-8)!
30P8 = 30! ÷ 22!
30P8 = (30*29*28*27*26*25*24*23)
30P8 = 235989936000 words
A^2 +b^2 =c^2
a^2 +27^2=365^2
a^2+ 729=133,225
a^2=133,225- 729
a^2=132,496
a^2= The square root of 132,496
a=364
(9m - 6)7
Distribute 7 to both sides
63m - 42
Add 42 to get 63m by itself
63m = 42
Divide both sides by 63
m = 42/63 or simplified, 2/3
