Answer:
11x^2 - 11x - 6
Step-by-step explanation:
I'm guessing you mean:
(10x^2 - x + 1 ) + (x^2 - 10x - 7)
First you combined like terms:
Such as :
10x^2 + x^2
-x - 10x
1 - 7
There's your answer.
11x^2 - 11x - 6
Answer:
F(n) = 6n
Step-by-step explanation:
An explicit sequence goes by the pattern: A0 + (n-1)d, where A0 is the starting term, n is the nth term in the sequence, and d is the common difference. The explicit formula for this sequence is F(n) = 6 + 6(n-1), or 6n

Step-by-step explanation:
Step-by-step explanation:
theta = 180 - 123 = 57 degree
arc length = 2 * pi * R * ( theta / 360)
= 2 * pi * R * ( 57 / 360)
= 0.994R cm
