Answer:
D.
Step-by-step explanation:
f(x)·g(x)=(x³+2x²+3x+1)(4x-5)
=
=
Use this formula: C=2πr. Divide 14/2 to get the radius. Substitute the radius into the formula.
The answer is 14pi units.

Answer:
The answer is B. f(x) = (x − 1)(x − 2)(x + 1)(x + 2)
Answer:
The smallest positive integer solution to the given system of congruences is 30.
Step-by-step explanation:
The given system of congruences is


where, m and n are positive integers.
It means, if the number divided by 5, then remainder is 0 and if the same number is divided by 11, then the remainder is 8. It can be defined as



Now, we can say that m>n because m and n are positive integers.
For n=1,


19 is not divisible by 5 so m is not an integer for n=1.
For n=2,



The value of m is 6 and the value of n is 2. So the smallest positive integer solution to the given system of congruences is

Therefore the smallest positive integer solution to the given system of congruences is 30.
