Answer:
(8-5)*(6+7+(8-6)+(7-5))
Step-by-step explanation:
The answer to your question is 55.93
Answer:
870
Step-by-step explanation:
Assuming you mean
30
Using the definition
n
= 
where n! = n(n - 1)(n - 2) ..... 3 × 2 × 1
Then
30
=
= 
Cancel the terms 28(27)... on numerator/ denominator, leaving
30
= 30 × 29 = 870
First you need to subtract 35 to get one equation =0.
x^2-10x-10=0 then use the quadratic formula (let me know if you need the formula of need to see these steps)
and solve to = approximately 8.87 and 1.12
