Answer:
3 Years
Step-by-step explanation:
7000*22% = 1540
4620/1540 = 3
1540 = the yearly interest
so it will take 3 years of $1540 of interest to get $4620.
Normally you would also have to take into account the interest plus the base varible but since it specifically says 7000 it makes it a simple problem.

There are 47,51,53,59,61,67,71, that is, 7 primes.
Answer:
(2n + 1)(n + 3) + (2n + 1)(n - 2)
= (2n + 1)(n + 3 + n - 2)
= (2n + 1)2n + 1)
= 4n² + 4n + 1
= 2(2n² + 2n) + 1
can see 2(2n² + 2n) is a multiple of 2 but 1 isnt a multiple of 2
=> 2(2n² + 2n) + 1 is not a multiple of 2
=> (2n + 1)(n + 3) + (2n + 1)(n - 2) is not a multiple of 2

Answer:
The area of rectangle is changing at the rate of 33 square inches per second.
Step-by-step explanation:
We are given the following information:
Let W be the width of the rectangle and L be the length of rectangle.
Rate of change of width = 
Rate of change of length = 
We have to find rate of change of area at W = 2 and L = 3.
Rate of change of area = 
Area of rectangle = Length × Width
Putting the values, we get
The area of rectangle is changing at the rate of 33 square inches per second.
