Answer:
n = 27
Step-by-step explanation:
14n = 11n + 81 (Given)
14n - 11n = 11n - 11n + 81 (Subtraction Property of Equality)
3n = 81 (Simplify)
(Division Property of Equality)
n = 27 (Simplify)
Answer:
336
Step-by-step explanation:
Using the definition of n
= n ! / (n- r) !
where n ! = n(n - 1)(n - 2).... × 3 × 2 × 1
8
= 8 ! / (8 - 3) !
= 8 ! / 5 !
= 
[ cancel 5(4)(3)(2)(1) on numerator/denominator
= 8 × 7 × 6 = 336
